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

2019-04-11T13:39:48Z

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.

Fix the following warning by adding a missing break: drivers/gpio/gpio-eic-sprd.c: In function ‘sprd_eic_irq_set_type’: drivers/gpio/gpio-eic-sprd.c:403:3: warning: this statement may fall through [-Wimplicit-fallthrough=] switch (flow_type) { ^~~~~~ drivers/gpio/gpio-eic-sprd.c:435:2: note: here default: ^~~~~~~ This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.

gpio: sprd: Fix incorrect irq type setting for the async EIC

2019-01-23T16:24:01Z

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

gpio: sprd: Fix the incorrect data register

2019-01-23T16:24:01Z

Since differnt type EICs have its own data register to read, thus fix the incorrect data register. Fixes: 25518e024e3a ("gpio: Add Spreadtrum EIC driver support") Cc: Signed-off-by: Neo Hou Signed-off-by: Baolin Wang Signed-off-by: Bartosz Golaszewski

gpio: eic: Add edge trigger emulation for EIC

2018-05-16T12:35:24Z

The Spreadtrum debounce EIC and latch EIC can not support edge trigger, but most GPIO users (like gpio-key driver) only use the edge trigger, thus the EIC driver need add some support to emulate the edge trigger to satisfy this requirement. Signed-off-by: Baolin Wang Signed-off-by: Linus Walleij

gpio: Add Spreadtrum EIC driver support

2018-03-27T13:51:17Z

The Spreadtrum digital-chip EIC controller has 4 sub-modules: debounce EIC, latch EIC, async EIC and sync EIC, and each sub-module can has multiple banks and each bank contains 8 EICs. Each EIC can only be used as input mode, and has the capability to trigger interrupts when detecting input signals. Signed-off-by: Baolin Wang Reviewed-by: Andy Shevchenko Signed-off-by: Linus Walleij
