Subject: [PATCH v4 0/4] clk: add BCM63268 timer clock and reset

Broadcom BCM63268 has a timer clock and reset controller which has the
following layout:
  #define POR_RESET_STATUS            (1 << 31)
  #define HW_RESET_STATUS             (1 << 30)
  #define SW_RESET_STATUS             (1 << 29)
  #define USB_REF_CLKEN               (1 << 18)
  #define UTO_EXTIN_CLKEN             (1 << 17)
  #define UTO_CLK50_SEL               (1 << 16)
  #define FAP2_PLL_CLKEN              (1 << 15)
  #define FAP2_PLL_FREQ_SHIFT         12
  #define FAP1_PLL_CLKEN              (1 << 11)
  #define FAP1_PLL_FREQ_SHIFT         8
  #define WAKEON_DSL                  (1 << 7)
  #define WAKEON_EPHY                 (1 << 6)
  #define DSL_ENERGY_DETECT_ENABLE    (1 << 4)
  #define GPHY_1_ENERGY_DETECT_ENABLE (1 << 3)
  #define EPHY_3_ENERGY_DETECT_ENABLE (1 << 2)
  #define EPHY_2_ENERGY_DETECT_ENABLE (1 << 1)
  #define EPHY_1_ENERGY_DETECT_ENABLE (1 << 0)

v4: add changes suggested by Stephen Boyd.
v3: add missing <linux/io.h> include to fix build warning
v2: add changes suggested by Stephen Boyd.
