2022-08-29clk: qcom: gcc-msm8916: move GPLL definitions upDmitry Baryshkov1-108/+108
Move GPLL definitions up, before the clock parent tables, so that we can use gpll hw clock fields in the parent_data/parent_hws tables.

2022-08-29clk: qcom: gcc-msm8916: use ARRAY_SIZE instead of specifying num_parentsDmitry Baryshkov1-54/+54
Use ARRAY_SIZE() instead of manually specifying num_parents. This makes adding/removing entries to/from parent_data easy and errorproof. This conversion fixes an issue present since the first version of this driver. For the gp1_clk_src, gp2_clk_src and gp3_clk_src it was impossible to select sleep_clk as a prent of the clock, since num_parents was limited to 3 rather than 4. Switching to use num_parents automatically makes sleep_clk available for selection.

CMU_MFCMSCL clock domain provides clocks for MFC (Multi-Format Codec), JPEG Codec and Scaler IP-cores. According to Exynos850 TRM, CMU_MFCMSCL generates MFC, M2M, MCSC and JPEG clocks for BLK_MFCMSCL.

All of those have to be enabled in order to read /sys/kernel/debug/clk/clk_summary file 2. When some user driver (e.g. exynos-sysmmu) disables some derived leaf clock, it can lead to CMU_TOP clocks disable, which then makes the system hang. To prevent that, the CLK_IS_CRITICAL flag is used, as CLK_IGNORE_UNUSED is not enough.

TREX D Core and P core clocks seem to be related to the BTS (Bus Traffic Shaper) inside the Exynos7885 SoC, and are needed for the SoC to function correctly. When clocks are cut from TREX D Core, the eMMC and the framebuffer stops working properly. Other unknown things may stop working as well.

"BUG: KASAN: stack-out-of-bounds in strncpy+0x30/0x68" Linux-ATF interface is using 16 bytes of SMC payload. In case clock name is longer than 15 bytes, string terminated NULL character will not be received by Linux. Add explicit NULL character at last byte to fix issues when clock name is longer. This fixes below bug reported by KASAN: ================================================================== BUG: KASAN: stack-out-of-bounds in strncpy+0x30/0x68 Read of size 1 at addr ffff0008c89a7410 by task swapper/0/1 CPU: 1 PID: 1 Comm: swapper/0 Not tainted 5.4.0-00396-g81ef9e7-dirty #3 Hardware name: Xilinx Versal vck190 Eval board revA (QSPI) (DT) Call trace: dump_backtrace+0x0/0x1e8 show_stack+0x14/0x20 dump_stack+0xd4/0x108 print_address_description.isra.0+0xbc/0x37c __kasan_report+0x144/0x198 kasan_report+0xc/0x18 __asan_load1+0x5c/0x68 strncpy+0x30/0x68 zynqmp_clock_probe+0x238/0x7b8 platform_drv_probe+0x6c/0xc8 really_probe+0x14c/0x418 driver_probe_device+0x74/0x130 __device_attach_driver+0xc4/0xe8 bus_for_each_drv+0xec/0x150 __device_attach+0x160/0x1d8 device_initial_probe+0x10/0x18 bus_probe_device+0xe0/0xf0 device_add+0x528/0x950 of_device_add+0x5c/0x80 of_platform_device_create_pdata+0x120/0x168 of_platform_bus_create+0x244/0x4e0 of_platform_populate+0x50/0xe8 zynqmp_firmware_probe+0x370/0x3a8 platform_drv_probe+0x6c/0xc8 really_probe+0x14c/0x418 driver_probe_device+0x74/0x130 device_driver_attach+0x94/0xa0 __driver_attach+0x70/0x108 bus_for_each_dev+0xe4/0x158 driver_attach+0x30/0x40 bus_add_driver+0x21c/0x2b8 driver_register+0xbc/0x1d0 __platform_driver_register+0x7c/0x88 zynqmp_firmware_driver_init+0x1c/0x24 do_one_initcall+0xa4/0x234 kernel_init_freeable+0x1b0/0x24c kernel_init+0x10/0x110 ret_from_fork+0x10/0x18 The buggy address belongs to the page: page:ffff0008f9be1c88 refcount:0 mapcount:0 mapping:0000000000000000 index:0x0 raw: 0008d00000000000 ffff0008f9be1c90 ffff0008f9be1c90 0000000000000000 raw: 0000000000000000 0000000000000000 00000000ffffffff page dumped because: kasan: bad access detected addr ffff0008c89a7410 is located in stack of task swapper/0/1 at offset 112 in frame: zynqmp_clock_probe+0x0/0x7b8 this frame has 3 objects: [32, 44) 'response' [64, 80) 'ret_payload' [96, 112) 'name' Memory state around the buggy address: ffff0008c89a7300: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ffff0008c89a7380: 00 00 00 00 f1 f1 f1 f1 00 04 f2 f2 00 00 f2 f2 >ffff0008c89a7400: 00 00 f3 f3 00 00 00 00 00 00 00 00 00 00 00 00 ^ ffff0008c89a7480: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ffff0008c89a7500: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ================================================================== Signed-off-by: Ian Nam <young.kwan.nam@xilinx.com> Signed-off-by: Shubhrajyoti Datta <shubhrajyoti.datta@xilinx.com> Link: https://lore.kernel.org/r/20220510070154.29528-3-shubhrajyoti.datta@xilinx.com Acked-by: Michal Simek <michal.simek@amd.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>

2022-08-23clk: core: Fix runtime PM sequence in clk_core_unprepare()Chen-Yu Tsai1-2/+1
In the original commit 9a34b45397e5 ("clk: Add support for runtime PM"), the commit message mentioned that pm_runtime_put_sync() would be done at the end of clk_core_unprepare(). This mirrors the operations in clk_core_prepare() in the opposite order. However, the actual code that was added wasn't in the order the commit message described. Move clk_pm_runtime_put() to the end of clk_core_unprepare() so that it is in the correct order.

2022-08-23clk: core: Honor CLK_OPS_PARENT_ENABLE for clk gate opsChen-Yu Tsai1-0/+28
In the previous commits that added CLK_OPS_PARENT_ENABLE, support for this flag was only added to rate change operations (rate setting and reparent) and disabling unused subtree. It was not added to the clock gate related operations. Any hardware driver that needs it for these operations will either see bogus results, or worse, hang. This has been seen on MT8192 and MT8195, where the imp_ii2_* clk drivers set this, but dumping debugfs clk_summary would cause it to hang.

Most of the clock related dt-binding header files are located in dt-bindings/clock folder. It would be good to keep all the similar header files at a single location. This was discovered while investigating the state of ownership of the files in include/dt-bindings/ according to the MAINTAINERS file. This change here is similar to commit 8e28918a85a0 ("dt-bindings: clock: Move ti-dra7-atl.h to dt-bindings/clock") and commit 35d35aae8177 ("dt-bindings: clock: Move at91.h to dt-bindigs/clock").
