2019-06-12pinctrl: meson-gx: add support for getting pinmux statusNeil Armstrong
In order to support the "pinmux status" command, use the common functions to get the pins count and names, and add the GX specific function to get the current function from registers. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Tested-by: Maxime Jourdan <mjourdan@baylibre.com>

2019-06-12pinctrl: meson-gx: fix GPIO_TEST_N and GPIOCLK_ groupsNeil Armstrong
The GPIO_TEST_N was in the wrong pmx group table, move it back with the AO groups, GPIODV_18 was missing, add it back, and finally the GPIOCLK_* group names were missing. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
2019-06-11pinctrl: imx: Define imx6_pinctrl_soc_info in .data sectionLukasz Majewski
This commit is necessary to be able to re-use the pinctrl code in early SPL to properly configure pins. The problem is that those "static" structures (without explicit initialization) are placed in the SDRAM area, which corresponds to u-boot proper (not even SPL). Hence, when one wants to configure pins before relocation via DTS/DM, the board hangs (imx6q SoC powered one) as only OCRAM area is available (0x009xxxxx). This commit prevents from this issue by moving the imx6_pinctrl_soc_info structure to data section (from BSS). Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Peng Fan <peng.fan@nxp.com>
