2020-08-20ARM: s3c24xx: move s3cmci pinctrl handling into board filesArnd Bergmann1-54/+17
Rather than call the internal s3c_gpio_cfgall_range() function through a platform header, move the code into the set_power callback that is already exported by the board, and add a default implementation. In DT mode, the code already does not set the pin config, so nothing changes there.

2020-07-24mmc: via-sdmmc: use generic power managementVaibhav Gupta1-25/+8
Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. This driver makes use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device(), pci_enable_wake() and pci_set_power_state() and to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use dev_get_drvdata() to get drv data. Compile-tested only.

2020-07-16treewide: Remove uninitialized_var() usageKees Cook1-1/+1
Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. In preparation for removing[2] the[3] macro[4], remove all remaining needless uses with the following script: git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \ xargs perl -pi -e \ 's/\buninitialized_var\(([^\)]+)\)/\1/g; s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;' drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid pathological white-space. No outstanding warnings were found building allmodconfig with GCC 9.3.0 for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64, alpha, and m68k.

2020-07-13mmc: core: Add MMC_CAP2_FULL_PWR_CYCLE_IN_SUSPENDYoshihiro Shimoda2-1/+4
The commit 5a36d6bcdf23 ("mmc: core: Add DT-bindings for MMC_CAP2_FULL_PWR_CYCLE") added the "full-pwr-cycle" property which is possible to perform a full power cycle of the card at any time. However, some environment (like r8a77951-salvator-xs) is possible to perform a full power cycle of the card in suspend via firmware (PSCI on arm-trusted-firmware). So, in worst case, since we are not doing a graceful shutdown of the eMMC device (just cut VCCQ while the eMMC is "sleeping") in suspend, it could lead to internal data corruptions. So, add MMC_CAP2_FULL_PWR_CYCLE_IN_SUSPEND to do a graceful shutdown which issues Power Off notification before entering system suspend.
