[PATCH 0/2] arm: mvebu: Remove comphy_update_map()

Convert Turris MOX's comphy_update_map() to board_fix_fdt() and then remove it.
Pali Rohár (2): arm: mvebu: turris_mox: Convert comphy_update_map() to board_fix_fdt() phy: marvell: Remove unused function comphy_update_map()
board/CZ.NIC/turris_mox/turris_mox.c | 48 +++++++++------------------- drivers/phy/marvell/comphy_core.c | 9 ------ drivers/phy/marvell/comphy_core.h | 9 ++++++ include/mvebu/comphy.h | 11 ------- 4 files changed, 24 insertions(+), 53 deletions(-)

Code in board_fix_fdt() already detects connected MOX modules so there is no need to have custom comphy_update_map() function for setting serdes speeds.
This change sets phy-mode for MOX SFP module (when present) to sgmii. Comphy driver then sets sgmii serdes speed for this module to 1.25G.

This weak function is not used anymore, so completely remove it.
Private struct comphy_map is not used by any board code anymore, so move it into private driver header file comphy_core.h.
