Most of functions and registers of the rk817 and rk808 are the same, so they can share allmost all codes.
Their specifications are as follows�� 1) The RK809 and RK809 consist of 5 DCDCs, 9 LDOs and have the same registers for these components except dcdc5. 2) The dcdc5 is a boost dcdc for RK817 and is a buck for RK809. 3) The RK817 has one switch but The Rk809 has two. Changes in V2: 1. initialize the pm_pwroff_fn to NULL. 2. use EXPORT_SYMBOL_GPL to export pm_power_off_prepare. 3. change patch 2/3/4/5 subjects. Changes in V3�� 1. change patch 4 subjects 2. replace pr_ with dev_ for printing in patch 2 3. modify switch1 and switch2 configs in patch 2 4. explain gpio information for rk809 and rk817 in patch 4 Changes in V4: 1. modify some codes for patch 2 and patch 5 according to comments 2. add reviewer mail lists for patch 3 and 4 Changes in V5: modify some codes for patch 1 according to reveiw comments for v3. 1) remove the pm_power_off_prepare() and replace with shutdown call-back from syscore 2) move the macro REGMAP_IRQ_M into the regmap.h and rename it REGMAP_IRQ_LINE 3) make some dev_warn() log clear Tony Xie (5): mfd: rk808: Add RK817 and RK809 support regulator: rk808: add RK809 and RK817 support. dt-bindings: mfd: rk808: Add binding information for RK809 and RK817. rtc: rk808: add RK809 and RK817 support. clk: RK808: add RK809 and RK817 support.
