2023-10-11pinctrl: cherryview: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-10-06pinctrl: cherryview: Avoid duplicated I/OAndy Shevchenko
In some cases we already read the value from the register followed by a reading of it again for other purposes, but the both reads are under the lock and bits we are insterested in are not going to change (they are not volatile from HW perspective). Hence, no need to read the same register twice. Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

Cleaning up the driver to use pm_ptr() and *_PM_OPS() macros that make it simpler and allows the compiler to remove those functions if built without CONFIG_PM and CONFIG_PM_SLEEP support. The lp_gpio_resume() is also assigned to .thaw and .restore members. This is not a problem as the function it enables input pins that had been disabled by firmware and repetion of that doesn't change the pin configuration, i.e. it is idempotent.

2023-08-15Merge patch series "Reuse common functions from pinctrl-intel"Andy Shevchenko
Raag Jadav <raag.jadav@intel.com> says: This series exports common pinctrl functions that are used across Intel specific platform drivers to PINCTRL_INTEL namespace and reuses them into Baytrail, Cherryview and Lynxpoint drivers. This helps reduce their code and memory footprint. X86 kernels are fairly unikernels such that pinctrl-intel driver is enabled by most Linux distributions and most Intel specific platform drivers (inside drivers/pinctrl/intel) depend on it. The only exception to this is Lynxpoint. But taking into account its fairly old age, it wouldn't suffer much from pinctrl-intel dependency. bloat-o-meter: ============== Intel: add/remove: 17/10 grow/shrink: 0/0 up/down: 375/-319 (56) Total: Before=9598, After=9654, chg +0.58% Baytrail: add/remove: 1/6 grow/shrink: 0/2 up/down: 41/-441 (-400) Total: Before=16538, After=16138, chg -2.42% Cherryview: add/remove: 1/6 grow/shrink: 2/0 up/down: 90/-272 (-182) Total: Before=18133, After=17951, chg -1.00% Lynxpoint: add/remove: 1/6 grow/shrink: 0/1 up/down: 24/-354 (-330) Total: Before=7836, After=7506, chg -4.21% Link: https://lore.kernel.org/r/20230814060311.15945-1-raag.jadav@intel.com Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

2023-06-06pinctrl: cherryview: Return correct value if pin in push-pull modeAndy Shevchenko
Currently the getter returns ENOTSUPP on pin configured in the push-pull mode. Fix this by adding the missed switch case. Fixes: ccdf81d08dbe ("pinctrl: cherryview: add option to set open-drain pin config") Fixes: 6e08d6bbebeb ("pinctrl: Add Intel Cherryview/Braswell pin controller support") Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
