leds: lgm-sso: Propagate error codes from callee to caller

2021-08-07T07:12:45+00:00

The one of the latest change to the driver reveals the problem that the error codes from callee aren't propagated to the caller of __sso_led_dt_parse(). Fix this accordingly. Fixes: 9999908ca1ab ("leds: lgm-sso: Put fwnode in any case during ->probe()") Fixes: c3987cd2bca3 ("leds: lgm: Add LED controller driver for LGM SoC") Reported-by: kernel test robot Signed-off-by: Andy Shevchenko Signed-off-by: Pavel Machek

leds: lgm-sso: Convert to use list_for_each_entry*() API

2021-08-03T21:46:12+00:00

Convert to use list_for_each_entry*() API insted of open coded variants. It saves few lines of code and makes iteasier to read and maintain. Signed-off-by: Andy Shevchenko Signed-off-by: Pavel Machek

leds: lgm-sso: Remove explicit managed GPIO resource cleanup

2021-08-03T21:46:12+00:00

The idea of managed resources is that they will be cleaned up automatically and in the proper order. Remove explicit GPIO cleanup. Signed-off-by: Andy Shevchenko Signed-off-by: Pavel Machek

leds: lgm-sso: Don't spam logs when probe is deferred

2021-08-03T21:46:11+00:00

When requesting GPIO line the probe can be deferred. In such case don't spam logs with an error message. This can be achieved by switching to dev_err_probe().

leds: lgm-sso: Put fwnode in any case during ->probe()

2021-08-03T21:46:10+00:00

fwnode_get_next_child_node() bumps a reference counting of a returned variable. We have to balance it whenever we return to the caller. All the same in fwnode_for_each_child_node() case.

leds: lgm: Fix up includes

2021-06-23T22:55:41+00:00

This driver is including the legacy GPIO header but the only thing it is using from that header is the wrong define for GPIOF_DIR_OUT. Fix it up by using GPIO_LINE_DIRECTION_OUT and including the correct consumer and driver headers. Cc: Amireddy Mallikarjuna reddy Signed-off-by: Linus Walleij Signed-off-by: Pavel Machek

leds: lgm-sso: Drop duplicate NULL check for GPIO operations

2021-05-28T10:00:01+00:00

Since GPIO operations are NULL-aware, we don't need to duplicate this check. Remove it and fold the rest of the code. Signed-off-by: Andy Shevchenko Signed-off-by: Pavel Machek

leds: lgm-sso: Remove unneeded of_match_ptr()

2021-05-28T10:00:00+00:00

LGM SSO is an OF dependent driver, so of_match_ptr() can be safely removed. Remove the unneeded of_match_ptr(). Signed-off-by: Andy Shevchenko Signed-off-by: Pavel Machek

leds: lgm-sso: Fix clock handling

2021-05-28T10:00:00+00:00

The clock handling has a few issues: - when getting second clock fails, the first one left prepared and enabled - on ->remove() clocks are unprepared and disabled twice Fix all these by converting to use bulk clock operations since both clocks are mandatory.

leds: LEDS_BLINK_LGM should depend on X86

2021-04-25T20:56:42+00:00

The Intel Lightning Mountain (LGM) Serial Shift Output controller (SSO) is only present on Intel Lightning Mountain SoCs. Hence add a dependency on X86, to prevent asking the user about this driver when configuring a kernel without Intel Lightning Mountain platform support. While at it, merge the other dependencies into a single statement. Signed-off-by: Geert Uytterhoeven Signed-off-by: Pavel Machek
