2022-07-06MLK-25902-1 gpio: adp5585: update adp5585 gpio driverAlice Guo
The adp5585 used on i.MX93 has 10 GPIOs, so we update ADP5585_MAXGPIO, ADP5585_BANK and ADP5585_BIT. GPIO_x_DIR equals to 0 for input and 1 for output. Make corresponding changes in adp5585_get_function. Initialize plat->dat_out and plat->dir in adp5585_probe. Reviewed-by: Haibo Chen <haibo.chen@nxp.com> Signed-off-by: Alice Guo <alice.guo@nxp.com>

2022-04-06ENGR00315894-60 GPIO: Modify driver mxc_gpio to support RDC SemaphoresYe.Li
For GPIO group which shared by multiple masters, it may set in RDC to shared and semaphore required. Before access the GPIO register, the GPIO driver must get the RDC semaphore, and release the semaphore after the GPIO register access. When CONFIG_MXC_RDC is set, the features related to RDC semaphores is enabled in mxc_gpio driver.

2021-10-11sunxi: Clean up inclusions of asm/arch/gpio.hSamuel Holland
As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will remove the asm/arch/gpio.h header. In preparation, clean up the various files that include it. Some files did not contain any GPIO code at all, so this header was completely unused. A few files contained only legacy platform-specific GPIO code for setting up pin muxes. They were left unchanged, as that code will be completely removed by the DM_PINCTRL migration. The remaining files contain some combination of DM_GPIO and legacy GPIO code. For those, switch to including asm/gpio.h (if it wasn't included already). Right now, this header provides both sets of functions, because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the right header to include once the DM_GPIO migration is complete and GPIO_EXTRA_HEADER is no longer needed.
