From: ChiaEn Wu <chiaen_wu@richtek.com> This patch series add MediaTek MT6370 PMIC support and add a index macro to <linear_range.h>. The MT6370 is a highly-integrated smart power management IC, which includes a single cell Li-Ion/Li-Polymer switching battery charger, a USB Type-C & Power Delivery (PD) controller, dual Flash LED current sources, a RGB LED driver, a backlight WLED driver, a display bias driver and a general LDO for portable devices. First, in this series of patches, 'dt-binding: mfd', 'mfd driver' has been applied by Lee in the v7. https://lore.kernel.org/all/YvJdpq0MWNPQZw5c@google.com/ https://lore.kernel.org/all/YvJdxEpC2cB58Bq9@google.com/ 'tcpci driver' has been applied by Greg in the v8. https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git/commit/?h=usb-next&id=c2a8ea5997fdfeb43eda259d5533234c3cae05d7 Second, the LED RGB driver is based on Andy's patch which moves led_init_default_state_get() to the global header. https://lore.kernel.org/all/20220805154907.32263-3-andriy.shevchenko@linux.intel.com/ In addition, we added a macro to the <linear_range.h> for declaring the linear_range struct simply (see patch v9-0005) and made some changes for MT6370 drivers (see v9 section of the change log below).
