mfd: mc13xxx: Fix a missing check of a register-read failure

2019-02-27T09:09:44+00:00

[ Upstream commit 9e28989d41c0eab57ec0bb156617a8757406ff8a ] When mc13xxx_reg_read() fails, "old_adc0" is uninitialized and will contain random value. Further execution uses "old_adc0" even when mc13xxx_reg_read() fails. The fix checks the return value of mc13xxx_reg_read(), and exits the execution when it fails.

mfd: cros_ec_dev: Add missing mfd_remove_devices() call in remove

[ Upstream commit 18e294ddafaeb80a1e2e10c9bd750a6cb8388d5b ] The driver adds different MFD child devices via mfd_add_devices() and hence it is required to call mfd_remove_devices() to remove MFD child devices.

mfd: axp20x: Add supported cells for AXP803

[ Upstream commit ea90e7b47f0a8bd2fe14e9a88f523de7c67db90a ] Parts of the AXP803 are compatible with their counterparts on the AXP813. These include the GPIO, ADC, AC and battery power supplies.

mfd: axp20x: Re-align MFD cell entries

2019-02-27T09:09:43+00:00

[ Upstream commit 753a8d083e085c6f552c7982749de4cc7c40e2ac ] In the axp20x driver, the various mfd_cell lists had varying amounts of indentation, sometimes even within the same list. For the axp288, there's no alignment at all. Re-align the right hand side of the assignments with the least amount of tabs possible. Also collapse the closing bracket and the opening bracket of the next entry onto the same line for the axp288, to be consistent with all the other mfd_cell lists. This patch is whitespace change only. No functionality is modified. Signed-off-by: Chen-Yu Tsai Signed-off-by: Oskari Lemmela Signed-off-by: Lee Jones Signed-off-by: Sasha Levin

mfd: qcom_rpm: write fw_version to CTRL_REG

2019-02-27T09:09:43+00:00

[ Upstream commit 504e4175829c44328773b96ad9c538e4783a8d22 ] This is required as part of the initialization sequence on certain SoCs. If these registers are not initialized, the hardware can be unresponsive. This fixes the driver on apq8060 (HP TouchPad device).

mfd: at91-usart: Add platform dependency

[ Upstream commit 628f3dfe4c7b35bbe63ec194ca6da857b00b0083 ] It doesn't make sense to present option MFD_AT91_USART by default if not building an AT91 kernel, as the drivers which depend on it are not available.
