| * | ARM: EXYNOS: Update CONFIG_ARCH_NR_GPIO for ExynosSachin Kamat2013-07-241-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the recent cleanup in Exynos platform code notably commits 17859bec ("ARM: EXYNOS: Do not select legacy Kconfig symbols any more") and b9222210 ("ARM: EXYNOS: Remove mach/gpio.h"), the definition of ARCH_NR_GPIOS got removed. This started causing problems on SoCs like Exynos4412 which have more than the default number of GPIOs. Thus define this number in KConfig file which takes care of current SoC requirements and provides scope for GPIO expanders. Without this patch we get the following errors during boot: gpiochip_add: gpios 251..258 (gpv0) failed to register samsung-pinctrl 106e0000.pinctrl: failed to register gpio_chip gpv0, error code: -22 samsung-pinctrl: probe of 106e0000.pinctrl failed with error -22 Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Cc: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically this code gets executed only during debugging i.e when DEBUG_LL & SAMSUNG_PM_DEBUG is on, so required only for UART used for debugging.

It went unnoticed so far because return value of clk API calls were not being checked at all in the samsung serial port driver. This patch should be backported to at least 3.10 stable kernel, since the serial port has not been working on s3c2440 since 3.10-rc5.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On EXYNOS5440 there is DRAM on the 36-bit address range. Hence this patch converts the MAX_PHYSMEM_BITS macro to 36 if LPAE is enabled for the ARM architecture. The conventional section size on EXYNOS is 256M due to sparsemem. Since EXYNOS5440 has memory in multiples of 1G in 32-bit and 36-bit range, this has now been modified to 31.

And clk-vf610 driver mistakenly supplies RMII clock (50 MHz) as the source to fec. This results in the situation that fec driver gets ref_freq as 50 MHz, while physically it runs at 66 MHz (fec module clock physically sources from ipg which runs at 66 MHz). That's why software expects MDC runs at 2.5 MHz, while the measurement tells it runs at 3.3 MHz.

| * | ARM i.MX53: Fix UART pad configurationPhilipp Zabel2013-07-151-16/+16
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | The current default pad configuration for UART RX and TX pads sets a 360k pull-down and writes 1 to a reserved bit (1 << 0). It doesn't seem right to me that in idle state, the UART has to keep the signal high against a pull-down resistor. This patch instead sets a 100k pull-up, which incidentally corresponds to the register reset value for all but one (MX53_PAD_KEY_ROW0__UART4_RXD_MUX) pad, and removes the write to the reserved bit.

The first of them was buggy (it did way much more than it needed to do) and the second one attempted to fix an issue introduced by the first one. Fixes from Srivatsa S Bhat revert both. - If autosleep triggers during system shutdown and the shutdown callbacks of some device drivers have been called already, it may crash the system. Fix from Liu Shuo prevents that from happening by making try_to_suspend() check system_state. - The ACPI memory hotplug driver doesn't clear its driver_data on errors which may cause a NULL poiter dereference to happen later. Fix from Toshi Kani. - The ACPI namespace scanning code should not try to attach scan handlers to device objects that have them already, which may confuse things quite a bit, and it should rescan the whole namespace branch starting at the given node after receiving a bus check notify event even if the device at that particular node has been discovered already.

* / arm: delete __cpuinit/__CPUINIT usage from all ARM usersPaul Gortmaker2013-07-1470-140/+64
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.
