[net-next v6 0/4] net: phy: realtek: Add support for PHY LEDs on

[net-next v6 0/4] net: phy: realtek: Add support for PHY LEDs on

[Michael Klein]

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

Re: [net-next v6 1/4] net: phy: realtek: Group RTL82* macro definitions

Even after your patch, the registers aren't sorted as you describe.

My recommendation would be:

- group register field definitions below register number definitions.
  let's call these register definition blocks.
- group register definition blocks by prefix (so blocks for the same PHY
  are together.)
- within each PHY block, order by page number and then register number.
- keep definitions that aren't registers separate.

The reason is, when someone comes along and adds more definitions, they
aren't going to be using the register definition to determine whether
it already exists or not, they're going to be using the register number
and/or bitfield.

So something like the below. It could do with more definitions for
register numbers and/or page numbers.
