2015-10-02pinctrl: imx25: ensure that a pin with id i is at position i in the info arrayUwe Kleine-König
The code in pinctrl-imx.c only works correctly if in the imx_pinctrl_soc_info passed to imx_pinctrl_probe we have: info->pins[i].number = i conf_reg(info->pins[i]) = 4 * i (which conf_reg(pin) being the offset of the pin's configuration register). When the imx25 specific part was introduced in b4a87c9b966f ("pinctrl: pinctrl-imx: add imx25 pinctrl driver") we had: info->pins[i].number = i + 1 conf_reg(info->pins[i]) = 4 * i . Commit 34027ca2bbc6 ("pinctrl: imx25: fix numbering for pins") tried to fix that but made the situation: info->pins[i-1].number = i conf_reg(info->pins[i-1]) = 4 * i which is hardly better but fixed the error seen back then. So insert another reserved entry in the array to finally yield: info->pins[i].number = i conf_reg(info->pins[i]) = 4 * i Fixes: 34027ca2bbc6 ("pinctrl: imx25: fix numbering for pins") Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2015-02-03pinctrl: imx25: fix numbering for pinsUwe Kleine-König
The pin id for a given tuple listed in a fsl,pins property is calculated by dividing the first entry (which is also a register offset) by 4. As the first available register is at offset 0x8 and configures the pad MX25_PAD_A10 the right id for this pin is 2. All other pins are off by one, too. This patch drops the definition MX25_PAD_RESERVE1 (together with its only use) and decrements all following values by 1.

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

This moves all the Freescale-related drivers (i.MX and MXS) to its own subdirectory to clear the view.
