2018-06-13	net: phy: broadcom: Fix bcm_write_exp()	Florian Fainelli	1	-3/+3
	[ Upstream commit 79fb218d97980d4fee9a64f4c8ff05289364ba25 ] On newer PHYs, we need to select the expansion register to write with setting bits [11:8] to 0xf. This was done correctly by bcm7xxx.c prior to being migrated to generic code under bcm-phy-lib.c which unfortunately used the older implementation from the BCM54xx days. Fix this by creating an inline stub: bcm_write_exp_sel() which adds the correct value (MII_BCM54XX_EXP_SEL_ER) and update both the Cygnus PHY and BCM7xxx PHY drivers which require setting these bits. broadcom.c is unchanged because some PHYs even use a different selector method, so let them specify it directly (e.g: SerDes secondary selector).

2015-10-08	net: phy: Broadcom Cygnus internal Etherent PHY driver	Arun Parameswaran	1	-0/+158
	Add support for the Broadcom Cygnus SoCs internal PHY's. The PHYs are 1000M/100M/10M capable with support for 'EEE' and 'APD' (Auto Power Down). This driver supports the following Broadcom Cygnus SoCs: - BCM583XX (BCM58300, BCM58302, BCM58303, BCM58305) - BCM113XX (BCM11300, BCM11320, BCM11350, BCM11360) The PHY's on these SoC's require some workarounds for stable operation, both during configuration time and during suspend/resume. This driver handles the application of the workarounds. Signed-off-by: Arun Parameswaran <arunp@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
