rockchip: pinctrl: rk3399: add support for I2C8

2017-11-25T23:39:08+00:00

The RK3399 has a total of 9 I2C controllers.  To support these, the
enum in periph.h is extended and the mapping from the IRQ numbers to
the peripheral-ids is extended to ensure that pinctrl requests are
passed through to the function configuring the I2C pins.

For I2C8, the pinctrl is implemented and tested (on a RK3399-Q7) using
communication with the FAN53555 connected on I2C8.

rockchip: pinctrl: rk3368: add pinctrl for SDMMC0

2017-09-30T22:33:33+00:00

Apparently, our earlier assumption that the BROM will always set up
the iomux for SDcard communication does not always hold true: when
booting U-Boot from the on-module (on the RK3368-uQ7) eMMC, the SDcard
pins are not set up and need to be configured by the pinctrl driver to
allow SD card access.

This change implements support for setting up the SDMMC pins in
pinctrl for the RK3368.

rockchip: pinctrl: rk3368: add SPI support

2017-08-13T15:12:25+00:00

To implement pinctrl support for the RK3368, we need to add the
bit-definitions to configure the IOMUX and tie these into the
pinctrl framework. This also adds the mapping from the IRQ# back
onto the periheral id for the SPI devices.

rockchip: pinctrl: rk3368: move IOMUX bit-definitions to pinctrl driver

2017-08-13T15:12:24+00:00

There is no real reason to keep the bit-definitions for the IOMUX in
the grf header file (which defines the register layout of the GRF block):
these should only be used by our pinctrl driver (with the possible
exception of early debug-init code in TPL/SPL).

This moves the relevant definitions from the grf_rk3368.h header
into the pinctrl driver pinctrl_rk3368.c.

rockchip: pinctrl: rk3368: add support for configuring the MMC pins

2017-08-13T15:12:23+00:00

The RK3368 has two SD/MMC controllers that can be used from U-Boot
both during SPL and for booting an OS from the full bootloader stage.
While both are configured to (mostly) sensible settings from the BROM,
additional configuration for the MMC controller is needed to configure
it to 8bit mode.

This adds pinctrl support for the MMC controller.

rockchip: pinctrl: rk3368: add GMAC (RGMII only) support

2017-08-13T15:12:23+00:00

To add GMAC (Gigabit Ethernet) support (limited to RGMII only at this
point), we need support for additional pin-configuration.  This commit
adds the pinctrl support for GMAC in RGMII mode:
 * adds a PERIPH_ID_GMAC and the mapping from IRQ number to PERIPH_ID
 * configures the RGMII pins
