pinctrl: samsung: use 'int' for register masks in Exynos

2021-05-19T08:29:31+00:00

[ Upstream commit fa0c10a5f3a49130dd11281aa27e7e1c8654abc7 ] The Special Function Registers on all Exynos SoC, including ARM64, are 32-bit wide, so entire driver uses matching functions like readl() or writel(). On 64-bit ARM using unsigned long for register masks: 1. makes little sense as immediately after bitwise operation it will be cast to 32-bit value when calling writel(), 2. is actually error-prone because it might promote other operands to 64-bit.

pinctrl: pinctrl-single: fix pcs_pin_dbg_show() when bits_per_mux is not zero

2021-05-14T08:50:01+00:00

[ Upstream commit bd85125ea88513f637a62a72e8949c579c5c0a87 ] A System Error (SError, followed by kernel panic) was detected when trying to print the supported pins in a pinctrl device which supports multiple pins per register. This change fixes the pcs_pin_dbg_show() in pinctrl-single driver when bits_per_mux is not zero. In addition move offset calculation and pin offset in register to common function.

pinctrl: core: Show pin numbers for the controllers with base = 0

[ Upstream commit 482715ff0601c836152b792f06c353464d826b9b ] The commit f1b206cf7c57 ("pinctrl: core: print gpio in pins debugfs file") enabled GPIO pin number and label in debugfs for pin controller. However, it limited that feature to the chips where base is positive number. This, in particular, excluded chips where base is 0 for the historical or backward compatibility reasons. Refactor the code to include the latter as well.

pinctrl: qcom: lpass lpi: use default pullup/strength values

commit 2a9be38099e338f597c14d3cb851849b01db05f6 upstream. If these fields are not set in dts, the driver will use these variables uninitialized to set the fields. Not only will it set garbage values for these fields, but it can overflow into other fields and break those. In the current sm8250 dts, the dmic01 entries do not have a pullup setting, and might not work without this change.
