From 0ba19cfc2a667ca986355e11d122c465482f12e2 Mon Sep 17 00:00:00 2001 From: Bin Gao Date: Mon, 25 Jul 2016 14:59:38 -0700 Subject: gpio: Add Intel WhiskeyCove PMIC GPIO driver This patch introduces a separate GPIO driver for Intel WhiskeyCove PMIC. This driver is based on gpio-crystalcove.c. Changes in v7: - Fixed various coding style comments from Andy Shevchenko Changes in v6: - Removed unnecessary wcove_gpio_remove() - Used devm_gpiochip_remove() instead of gpiochip_remove() - Various coding style changes per Mika's comment Changes in v5: - Revisited the interrupt handler code to iterate until all pending interrupts are handled. This change is to avoid missing interrupt when we're inside the interrupt handler. - Used regmap_bulk_read() to read address adjacent registers. Changes in v4: - Converted CTLI_INTCNT_XX macros to less verbose ones INT_DETECT_XX. - Add comments about why there is no .pm for the driver. - Header files re-ordered. - Various coding style change to address Andy's comments. Changes in v3: - Fixed the year in copyright line(2015-->2016). - Removed DRV_NAME macro. - Added kernel-doc for regmap_irq_chip of the wcove_gpio structure. - Line length fix. Changes in v2: - Typo fix (Whsikey --> Whiskey). - Included linux/gpio/driver.h instead of linux/gpio.h - Implemented .set_single_ended(). - Added GPIO register description. - Replaced container_of() with gpiochip_get_data(). - Removed unnecessary "if (gpio > WCOVE_VGPIO_NUM" check. - Removed the device id table and added MODULE_ALIAS().
