pinctrl: meson: fix uart_ao_b for GXBB and GXL/GXM

2017-01-19T09:36:25+00:00

The GXBB and GXL/GXM pinctrl drivers had a configuration which conflicts
with uart_ao_a. According to the GXBB ("S905") datasheet the AO UART
functions are:
- GPIOAO_0: Func1 = UART_TX_AO_A (bit 12), Func2 = UART_TX_AO_B (bit 26)
- GPIOAO_1: Func1 = UART_RX_AO_A (bit 11), Func2 = UART_RX_AO_B (bit 25)
- GPIOAO_4: Func2 = UART_TX_AO_B (bit 24)
- GPIOAO_5: Func2 = UART_RX_AO_B (bit 25)

The existing definition for uart_AO_A already uses GPIOAO_0 and GPIOAO_1.
The old definition of uart_AO_B however was broken, as it used GPIOAO_0
for TX (which would be fine) and two pins (GPIOAO_1 and GPIOAO_5) for RX
(which does not make any sense).

This fixes the uart_AO_B configuration by moving it to GPIOAO_4 and
GPIOAO_5 (it would be possible to use GPIOAO_0 and GPIOAO_1 in theory,
but all existing hardware uses uart_AO_A there).
The fix for GXBB and GXL/GXM is identical since it seems that these
specific pins are identical on both SoC variants.

pinctrl: meson: fix gpio request disabling other modes

2016-12-29T20:04:45+00:00

The pinctrl_gpio_request is called with the "full" gpio number, already
containing the base, then meson_pmx_request_gpio is then called with the
final pin number.
Remove the base addition when calling meson_pmx_disable_other_groups.

pinctrl: meson: Add GXL pinctrl definitions

2016-11-04T22:05:06+00:00

Add support for the Amlogic Meson GXL SoC, this is a partially complete
definition only based on the Amlogic Vendor tree.

This definition differs a lot from the GXBB and needs a separate entry.

pinctrl: amlogic: gxbb: add nand pins

2016-09-15T12:14:51+00:00

Add EE domains pins for the NAND flash controller.
Even tough we have no driver for the NAND flash controller yet, we need
to have these pins in pinctrl as the actual pin are shared with the spifc
controller. The bootloader on the S905-P200 setup pinmux for the NAND
controller so we need the kernel to properly deactivate this if necessary.
