This is a note to let you know that I have just added a patch titled pinctrl: imx25: ensure that a pin with id i is at position i in the info array to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.8-ckt10. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.19.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 546560060b815a37c0d3231c0cc68ecfcde3c80c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= <u.kleine-koenig@pengutronix.de> Date: Wed, 23 Sep 2015 16:35:09 +0200 Subject: [PATCH 051/120] pinctrl: imx25: ensure that a pin with id i is at position i in the info array MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 9911a2d5e9d14e39692b751929a92cb5a1d9d0e0 upstream. 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> Signed-off-by: Kamal Mostafa <kamal@canonical.com> --- drivers/pinctrl/freescale/pinctrl-imx25.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) -- 1.9.1
