[ Upstream commit d8b94c9ff96c2024a527086d850eb0b314337ff9 ] Certain SoC are missing the middle part gpios in consecutive pins, it's better to check if mtk_pin_desc is a valid pin for the extensibility Signed-off-by: Sam Shih <sam.shih@mediatek.com> Acked-by: Sean Wang <sean.wang@mediatek.com> Link: https://lore.kernel.org/r/20210914085137.31761-5-sam.shih@mediatek.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Stable-dep-of: 705c79101ccf ("smb: client: fix use-after-free in cifs_oplock_break") Signed-off-by: Sasha Levin <sashal@kernel.org>
2024-05-17pinctrl: mediatek: paris: Rework support for PIN_CONFIG_{INPUT,OUTPUT}_ENABLEChen-Yu Tsai1-27/+11
[ Upstream commit c5d3b64c568a344e998830e0e94a7c04e372f89b ] There is a misinterpretation of some of the PIN_CONFIG_* options in this driver library. PIN_CONFIG_OUTPUT_ENABLE should refer to a buffer or switch in the output direction of the electrical path. The MediaTek hardware does not have such a thing. The driver incorrectly maps this option to the GPIO function's direction. Likewise, PIN_CONFIG_INPUT_ENABLE should refer to a buffer or switch in the input direction. The hardware does have such a mechanism, and is mapped to the IES bit. The driver however sets the direction in addition to the IES bit, which is incorrect. On readback, the IES bit isn't even considered. Ironically, the driver does not support readback for PIN_CONFIG_OUTPUT, while its readback of PIN_CONFIG_{INPUT,OUTPUT}_ENABLE is what it should be doing for PIN_CONFIG_OUTPUT. Rework support for these three options, so that PIN_CONFIG_OUTPUT_ENABLE is completely removed, PIN_CONFIG_INPUT_ENABLE is only linked to the IES bit, and PIN_CONFIG_OUTPUT is linked to the GPIO function's direction and output level.

2024-05-17pinctrl: mediatek: paris: Fix PIN_CONFIG_INPUT_SCHMITT_ENABLE readbackChen-Yu Tsai1-0/+2
[ Upstream commit 08f66a8edd08f6f7cfa769c81634b29a2b123908 ] In the generic pin config library, readback of some options are handled differently compared to the setting of those options: the argument value is used to convey enable/disable of an option in the set path, but success or -EINVAL is used to convey if an option is enabled or disabled in the debugfs readback path. PIN_CONFIG_INPUT_SCHMITT_ENABLE is one such option. Fix the readback of the option in the mediatek-paris library, so that the debugfs dump is not showing "input schmitt enabled" for pins that don't have it enabled.

2024-05-17pinctrl: mediatek: paris: Rework mtk_pinconf_{get,set} switch/case logicChen-Yu Tsai1-83/+61
[ Upstream commit 9b780fa1ff14663c2e0f07ad098b96b8337f27a4 ] The current code deals with optional features by testing for the function pointers and returning -ENOTSUPP if it is not valid. This is done for multiple pin config settings and results in the code that handles the supporting cases to get indented by one level. This is aggrevated by the fact that some features require another level of conditionals. Instead of assigning the same error code in all unsupported optional feature cases, simply have that error code as the default, and break out of the switch/case block whenever a feature is unsupported, or an error is returned. This reduces indentation by one level for the useful code. Also replace the goto statements with break statements. The result is the same, as the gotos simply exit the switch/case block, which can also be achieved with a break statement. With the latter the intent is clear and easier to understand.

2021-07-23pinctrl: mediatek: Fix fallback behavior for bias_set_comboHsin-Yi Wang1-5/+3
Some pin doesn't support PUPD register, if it fails and fallbacks with bias_set_combo case, it will call mtk_pinconf_bias_set_pupd_r1_r0() to modify the PUPD pin again. Since the general bias set are either PU/PD or PULLSEL/PULLEN, try bias_set or bias_set_rev1 for the other fallback case. If the pin doesn't support neither PU/PD nor PULLSEL/PULLEN, it will return -ENOTSUPP.

Commit 42a46434e9b1 ("pinctrl: add lock in mtk_rmw function.") uses mutex lock in mtk_rmw. However the function is possible called from atomic context. For example call trace: mutex_lock+0x28/0x64 mtk_rmw+0x38/0x80 [snip] max98357a_daiops_trigger+0x8c/0x9c soc_pcm_trigger+0x5c/0x10c The max98357a_daiops_trigger() could run in either atomic or non-atomic context. As a result, dmesg shows some similar messages: "BUG: sleeping function called from invalid context at kernel/locking/mutex.c:254". Uses spin lock in mtk_rmw instead.

2020-10-07pinctrl: mediatek: Free eint data on failureEnric Balletbo i Serra1-6/+18
The pinctrl driver can work without the EINT resource, but, if it is expected to have this resource but the mtk_build_eint() function fails after allocating their data (because can't get the resource or can't map the irq), the data is not freed and you end with a NULL pointer dereference. Fix this by freeing the data if mtk_build_eint() fails, so pinctrl still works and doesn't hang. This is noticeable after commit f97dbf48ca43 ("irqchip/mtk-sysirq: Convert to a platform driver") on MT8183 because, due this commit, the pinctrl driver fails to map the irq and spots the following bug: [ 1.947597] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000004 [ 1.956404] Mem abort info: [ 1.959203] ESR = 0x96000004 [ 1.962259] EC = 0x25: DABT (current EL), IL = 32 bits [ 1.967565] SET = 0, FnV = 0 [ 1.970613] EA = 0, S1PTW = 0 [ 1.973747] Data abort info: [ 1.976619] ISV = 0, ISS = 0x00000004 [ 1.980447] CM = 0, WnR = 0 [ 1.983410] [0000000000000004] user address but active_mm is swapper [ 1.989759] Internal error: Oops: 96000004 [#1] PREEMPT SMP [ 1.995322] Modules linked in: [ 1.998371] CPU: 7 PID: 1 Comm: swapper/0 Not tainted 5.9.0-rc1+ #44 [ 2.004715] Hardware name: MediaTek krane sku176 board (DT) [ 2.010280] pstate: 60000005 (nZCv daif -PAN -UAO BTYPE=--) [ 2.015850] pc : mtk_eint_set_debounce+0x48/0x1b8 [ 2.020546] lr : mtk_eint_set_debounce+0x34/0x1b8 [ 2.025239] sp : ffff80001008baa0 [ 2.028544] x29: ffff80001008baa0 x28: ffff0000ff7ff790 [ 2.033847] x27: ffff0000f9ec34b0 x26: ffff0000f9ec3480 [ 2.039150] x25: ffff0000fa576410 x24: ffff0000fa502800 [ 2.044453] x23: 0000000000001388 x22: ffff0000fa635f80 [ 2.049755] x21: 0000000000000008 x20: 0000000000000000 [ 2.055058] x19: 0000000000000071 x18: 0000000000000001 [ 2.060360] x17: 0000000000000000 x16: 0000000000000000 [ 2.065662] x15: ffff0000facc8470 x14: ffffffffffffffff [ 2.070965] x13: 0000000000000001 x12: 00000000000000c0 [ 2.076267] x11: 0000000000000040 x10: 0000000000000070 [ 2.081569] x9 : ffffaec0063d24d8 x8 : ffff0000fa800270 [ 2.086872] x7 : 0000000000000000 x6 : 0000000000000011 [ 2.092174] x5 : ffff0000fa800248 x4 : ffff0000fa800270 [ 2.097476] x3 : ffff8000100c5000 x2 : 0000000000000000 [ 2.102778] x1 : 0000000000000000 x0 : 0000000000000000 [ 2.108081] Call trace: [ 2.110520] mtk_eint_set_debounce+0x48/0x1b8 [ 2.114870] mtk_gpio_set_config+0x5c/0x78 [ 2.118958] gpiod_set_config+0x5c/0x78 [ 2.122786] gpiod_set_debounce+0x18/0x28 [ 2.126789] gpio_keys_probe+0x50c/0x910 [ 2.130705] platform_drv_probe+0x54/0xa8 [ 2.134705] really_probe+0xe4/0x3b0 [ 2.138271] driver_probe_device+0x58/0xb8 [ 2.142358] device_driver_attach+0x74/0x80 [ 2.146532] __driver_attach+0x58/0xe0 [ 2.150274] bus_for_each_dev+0x70/0xc0 [ 2.154100] driver_attach+0x24/0x30 [ 2.157666] bus_add_driver+0x14c/0x1f0 [ 2.161493] driver_register+0x64/0x120 [ 2.165319] __platform_driver_register+0x48/0x58 [ 2.170017] gpio_keys_init+0x1c/0x28 [ 2.173672] do_one_initcall+0x54/0x1b4 [ 2.177499] kernel_init_freeable+0x1d0/0x238 [ 2.181848] kernel_init+0x14/0x118 [ 2.185328] ret_from_fork+0x10/0x34 [ 2.188899] Code: a9438ac1 12001266 f94006c3 121e766a (b9400421) [ 2.194991] ---[ end trace 168cf7b3324b6570 ]--- [ 2.199611] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b [ 2.207260] SMP: stopping secondary CPUs [ 2.211294] Kernel Offset: 0x2ebff4800000 from 0xffff800010000000 [ 2.217377] PHYS_OFFSET: 0xffffb50500000000 [ 2.221551] CPU features: 0x0240002,2188200c [ 2.225811] Memory Limit: none [ 2.228860] ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b ]--- Fixes: 89132dd8ffd2 ("pinctrl: mediatek: extend eint build to pinctrl-mtk-common-v2.c") Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Sean Wang <sean.wang@kernel.org> Link: https://lore.kernel.org/r/20201001142511.3560143-1-enric.balletbo@collabora.com [rebased on changed infrastructure] Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
