[net-next v7 0/6] net: phy: realtek: Add support for PHY LEDs

[Michael Klein]

Changes in V7:
- Remove some unused macros (patch 1)
- Add more register defines for RTL8211F (patch 3)
- Revise macro definition order once more (patch 4)

Changes in V6:
- fix macro definition order (patch 1)
- introduce two more register defines (patch 2)

Changes in V5:
- Split cleanup patch and improve code formatting

Changes in V4:
- Change (!ret) to (ret == 0)
- Replace set_bit() by __set_bit()

Changes in V3:
- move definition of rtl8211e_read_ext_page() to patch 2
- Wrap overlong lines

Changes in V2:
- Designate to net-next
- Add ExtPage access cleanup patch as suggested by Andrew Lunn

[net-next v7 6/6] net: phy: realtek: Add support for PHY LEDs on RTL8211E

[Michael Klein]

Like the RTL8211F, the RTL8211E PHY supports up to three LEDs.
Add netdev trigger support for them, too.
