Input: bcm_iproc_tsc - drop of_match_ptr for ID table

2023-03-17T11:17:37Z

The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here). This also fixes !CONFIG_OF error: Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20230312131514.351603-4-krzysztof.kozlowski@linaro.org Signed-off-by: Dmitry Torokhov

Input: remove dev_err() usage after platform_get_irq()

2019-08-14T17:49:01Z

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).

Input: bcm_iproc_tsc - use syscon to access shared registers

2016-04-06T23:11:56Z

In Cygnus SOC touch screen controller registers are shared with ADC and flex timer. Using readl/writel could lead to race condition. So touch screen driver is enhanced to support register access using syscon framework API's to take care of mutually exclusive access.
