* regulator: Fix an s5m8767 build failureSamuel Ortiz2012-07-30
| | | | | | | | | | | | | Due to a merge conflict we are getting this: drivers/regulator/s5m8767.c: In function ‘s5m8767_pmic_probe’: drivers/regulator/s5m8767.c:575:2: error: implicit declaration of function ‘s5m_reg_write’ [-Werror=implicit-function-declaration] This is fixed by fully converting this driver to the new s5m API.

Fix up mostly trivial conflicts, with the exception of drivers/usb/host/ehci-omap.c in particular, which had some re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI: centralize controller initialization") that clashed with commit 2761a6394516 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues"). In particular, commit 2761a6394516 moved the usb_add_hcd() to the *middle* of the reset sequence, which clashes fairly badly with the reset sequence re-organization (although it could have been done inside the new omap_ehci_init() function). I left that part of commit 2761a6394516 just undone. * tag 'mfd-3.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (110 commits) mfd: Ensure AB8500 platform data is passed through db8500-prcmu to MFD Core mfd: Arizone core should select MFD_CORE mfd: Fix arizona-irq.c build by selecting REGMAP_IRQ mfd: Add debug trace on entering and leaving arizone runtime suspend mfd: Correct tps65090 cell names mfd: Remove gpio support from tps6586x core driver ARM: tegra: defconfig: Enable tps6586x gpio gpio: tps6586x: Add gpio support through platform driver mfd: Cache tps6586x register through regmap mfd: Use regmap for tps6586x register access. mfd: Use devm managed resources for tps6586x input: Add onkey support for 88PM80X PMIC mfd: Add support for twl6041 mfd: Fix twl6040 revision information mfd: Matches should be NULL when populate anatop child devices input: ab8500-ponkey: Create AB8500 domain IRQ mapping mfd: Add missing out of memory check for pcf50633 Documentation: Describe the AB8500 Device Tree bindings mfd: Add tps65910 32-kHz-crystal-input init mfd: Drop modifying mc13xxx driver's id_table in probe ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is in preparation for teaching async_synchronize_full() to sync all pending async work, and not just on the async_running domain. This conversion is functionally equivalent, just embedding the existing list in a new async_domain type. The .registered attribute is used in a later patch to distinguish between domains that want to be flushed by async_synchronize_full() versus those that only expect async_synchronize_{full|cookie}_domain to be used for flushing.

Yest another reason is in current code if gpio_request() returns error, the rest of the code still calls gpio_direction_output to config buck_gpios and buck_ds gpios. This looks wrong to me.

Especially, S2MPS11 is designed for high performance Samsung application processor. Signed-off-by: Sangbeom Kim <sbkim73@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
| * | regulator: tps65910: correct init value of n_voltagesLaxman Dewangan2012-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent change in the core driver to get the maximum voltage is based on the (n_voltages -1) steps of voltage. For the tps65910, the (n_voltages -1)th step voltage is calculated based on the callback function list_voltage. This function direct maps the datasheet and adjust the first few steps for initial voltage as per datasheet, and hence initialize the n_voltages based on datasheet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is ok to request current limit with min_uA < chip->min_uA and max_uA > chip->max_uA. We need to set min_uA = chip->min_uA if (min_uA < chip->min_uA), this ensures the equation to calcuate selator does not return negative number. Also set max_uA = chip->max_uA if (max_uA > chip->max_uA), as suggested by Sonic.
