* sunxi: gpio: Add .xlate function for gpio phandle resolutionChen-Yu Tsai2016-07-31-0/+16
| | | | | | | | | | | | | sunxi uses a 2 cell phandle for gpio bindings. Also there are no seperate nodes for each pin bank. Add a custom .xlate function to map gpio phandles to the correct pin bank device. This fixes gpio_request_by_name usage.

* sunxi: gpio: convert bind() to use driver dataStephen Warren2016-05-26-40/+50
| | | | | | | | | | | Now that the DM core sets driver_data before calling bind(), this driver can make use of driver_data to determine the set of child devices to create, rather than manually re-implementing the matching logic in code.

* sunxi: Add a bunch of missing compatible strings to sunxi_gpio.cHans de Goede2016-03-23-1/+14
| | | | | | | | | | | The kernel has different compatible strings for the pio block because the pin-muxing is different on all the different SoCs, but sunxi_gpio.c only support the basic gpio functionality, which is identical everywhere. Add the missing compatible strings for various SoC models. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

* sunxi: gpio: Add support for the gpio banks which are part of the R-io clusterHans de Goede2015-08-14-4/+18
| | | | | | | | | | | | | sun6i and later have a couple of io-blocks which are shared between the main CPU core and the "R" cpu which is small embedded cpu which can be active while the main system is suspended. These gpio banks sit at a different mmio address then the normal banks, and have a separate devicetree node and compatible, this adds support for these banks to the sunxi-gpio code when built with device-model support.

* sunxi: axp: Remove non driver-model support from the axp gpio codeHans de Goede2015-05-04-32/+0
| | | | | | | | | | | | | | Now that all sunxi boards are using driver-model for gpio (*), we can remove the non driver-model support from the axp gpio code, and the glue to call into the axp gpio code from the sunxi_gpio non driver-model code. *) For the regular u-boot build, SPL still uses non driver-model gpio for now, but the SPL never uses axp gpios support and we were already not building axp-gpio support for the SPL.

* sunxi: axp: Move axp gpio code to a separate axpi-gpio driverHans de Goede2015-05-04-11/+6
| | | | | | | | | | | | | | | | | | | | Move the axp-gpio code out of the drivers/power/axp*.c code, and into a new separate axpi-gpio driver. This change drops supports for the gpio3 pin on the axp209, as that requires special handling, and no boards are using it. Besides cleaning things up by moving the code to a separate driver, as a bonus this change also adds support for the (non vusb) gpio pins on the axp221 and the gpio pins on the axp152. The new axp-gpio driver gets its own Kconfig option, and is only enabled on boards which need it. Besides that it only gets enabled in the regular u-boot build and not for the SPL as we never need it in the SPL.

| | | | | | | | | | | | | Sunxi platforms have different possible mmc pin mux setups (except for mmc0), which are different across platforms. This lets users configure which is used through the CONFIG_MMC*_PINS Kconfig options.

* sunxi: gpio: Add support for gpio pins on the AXP209 pmicHans de Goede2015-01-14-0/+30
| | | | | | | | | | | | | | | | | | | | | | Some boards use GPIO-s on the pmic, one example of this is the A13-OLinuXino board, which uses gpio0 of the axp209 for the lcd-power signal. This commit adds support for gpio pins on the AXP209 pmic, the sunxi_gpio.c changes are universal, adding gpio support for the other AXP pmics (when necessary) should be a matter of adding the necessary axp_gpio_foo functions to their resp. drivers, and add "#define AXP_GPIO" to their header file. Note this commit only adds support for the non device-model version of the gpio code, patches for adding support to the device-model version are very welcome. The string representation for these gpio-s is AXP0-#, the 0 in the AXP0 prefix is there in case we need to support gpio-s on more then 1 pmic in the future. At least A80 boards have 2 pmics, and we may end up needing to support gpio-s on both. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| | | | | | | | | | | | It does not make sense to make gpio_direction_input() return the gpio input status. The return value of gpio_direction_input() is inconsistent if CONFIG_DM_GPIO is defined. And we don't need to call gpio_direction_input() int sunxi_mmc_getcd(). Just init the gpio once in mmc_resource_init() is enough.
