ARM: uniphier: use (devm_)ioremap() instead of map_sysmem()

2016-07-23T15:13:10Z

This does not have much impact on behavior, but makes code look more more like Linux. The use of devm_ioremap() often helps to delete .remove callbacks entirely. Signed-off-by: Masahiro Yamada

dm: gpio: MPC85XX GPIO platform data support

2016-07-11T20:06:44Z

Define a platform data structure for the MPC85XX GPIO driver to allow use of the driver without device tree. Users should define the GPIO blocks for their platform like this: struct mpc85xx_gpio_plat gpio_blocks[] = { { .addr = 0x130000, .ngpios = 32, }, { .addr = 0x131000, .ngpios = 32, }, }; U_BOOT_DEVICES(my_platform_gpios) = { { "gpio_mpc85xx", &gpio_blocks[0] }, { "gpio_mpc85xx", &gpio_blocks[1] }, }; This is intended to build upon the recent submission of the base MPC85XX driver from Mario Six. We need to use that new driver without dts support and this patch gives us that flexibility. This has been tested on a Freescale T2080 CPU, although only the first GPIO block.

gpio: pca953x: Fix register reading past 8th GPIO

2016-06-19T23:05:55Z

A bug in the pca953x driver prevents correct reading of GPIO input values beyond the 8th GPIO; all values are reported as zero. Setting of GPIO output values is not affected. This patch fixes the reading behavior. Signed-off-by: Mario Six Reviewed-by: Peng Fan Acked-by: Simon Glass

gpio: at91: Fix pullup/pulldown configuration on PIO3

2016-06-12T21:49:38Z

On systems with PIO3 (SAMA5D3/D4/..), the pullup and pulldown configuration is mutualy exclusive. This patch assures that the opposite pull resistor gets disabled before the requested pull resistor is enabled. This changes behavior of at91_set_pio_pulldown() such that the pullup is only disabled if pulldown is to be enabled. This changes behavior of at91_set_pio_pullup() such that the pulldown is only disabled if pullup is to be enabled.

Now that we have set up pin control in cpu_init_r(), remove the duplicated codes in the broadwell gpio driver. Signed-off-by: Bin Meng Reviewed-by: Stefan Roese Reviewed-by: Simon Glass

x86: Probe pinctrl driver in cpu_init_r()

2016-06-12T04:19:35Z

At present pinctrl driver gets probed in ich6_gpio driver's probe routine, which has two issues: - Pin's PADs only gets configured when GPIO driver is probed, which is not done by default. This leaves the board in a partially functional state as we must initialize PADs correctly to get perepherals fully working. - The probe routine of pinctrl driver is called multiple times, as normally there are multiple GPIO controllers. It should really be called just once. Move the call to syscon_get_by_driver_data() from ich6_gpio driver to cpu_init_r().
