gpio: eic-sprd: Make the irqchip immutable

2022-12-30T15:57:27+00:00

Remove the irq_chip from pmic_eic structure, use the various calls by defining the statically irq_chip structure. Signed-off-by: Cixi Geng Reviewed-by: Baolin Wang Signed-off-by: Bartosz Golaszewski

gpio: Get rid of duplicate of_node assignment in the drivers

2021-12-17T16:39:35+00:00

GPIO library does copy the of_node from the parent device of the GPIO chip, there is no need to repeat this in the individual drivers. Remove these assignment all at once. For the details one may look into the of_gpio_dev_init() implementation. While at it, remove duplicate parent device assignment where it is the case.

gpio: eic-sprd: break loop when getting NULL device resource

2020-12-09T08:41:49+00:00

EIC controller have unfixed numbers of banks on different Spreadtrum SoCs, and each bank has its own base address, the loop of getting there base address in driver should break if the resource gotten via platform_get_resource() is NULL already. The later ones would be all NULL even if the loop continues.

treewide: Use fallthrough pseudo-keyword

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

Revert "gpio: eic-sprd: Use devm_platform_ioremap_resource()"

2020-04-02T07:39:09+00:00

This reverts commit 0f5cb8cc27a266c81e6523b436479802e9aafc9e. This commit will cause below warnings, since our EIC controller can support differnt banks on different Spreadtrum SoCs, and each bank has its own base address, we will get invalid resource warning if the bank number is less than SPRD_EIC_MAX_BANK on some Spreadtrum SoCs. So we should not use devm_platform_ioremap_resource() here to remove the warnings.

gpio: eic: sprd: Fix the incorrect EIC offset when toggling

2019-10-01T09:50:40+00:00

When toggling the level trigger to emulate the edge trigger, the EIC offset is incorrect without adding the corresponding bank index, thus fix it.

gpio: Remove dev_err() usage after platform_get_irq()

2019-08-05T11:25:34+00:00

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).

gpio: eic: sprd: Fix incorrect irq type setting for the sync EIC

2019-04-11T13:39:48+00:00

When setting sync EIC as IRQ_TYPE_EDGE_BOTH type, we missed to set the SPRD_EIC_SYNC_INTMODE register to 0, which means detecting edge signals. Thus this patch fixes the issue.
