2019-03-21net: phy: Prepare for moving Omega out of bcm7xxxFlorian Fainelli
The Omega PHY entry was added to bcm7xxx.c out of convenience and this breaks the one driver per product line paradigm that was applied up until now. Since the AFE initialization is shared between Omega and BCM7xxx move the relevant functions to bcm-phy-lib.[ch]. No functional changes introduced.

2018-05-23net: phy: broadcom: Fix auxiliary control register readsFlorian Fainelli
We are currently doing auxiliary control register reads with the shadow register value 0b111 (0x7) which incidentally is also the selector value that should be present in bits [2:0]. Fix this by using the appropriate selector mask which is defined (MII_BCM54XX_AUXCTL_SHDWSEL_MASK). This does not have a functional impact yet because we always access the MII_BCM54XX_AUXCTL_SHDWSEL_MISC (0x7) register in the current code. This might change at some point though.

2018-04-27drivers: net: replace UINT64_MAX with U64_MAXJisheng Zhang
U64_MAX is well defined now while the UINT64_MAX is not, so we fall back to drivers' own definition as below: #ifndef UINT64_MAX #define UINT64_MAX (u64)(~((u64)0)) #endif I believe this is in one phy driver then copied and pasted to other phy drivers. Replace the UINT64_MAX with U64_MAX to clean up the source code. Signed-off-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-06net: phy: broadcom: Use strlcpy() for ethtool::get_stringsFlorian Fainelli
Our statistics strings are allocated at initialization without being bound to a specific size, yet, we would copy ETH_GSTRING_LEN bytes using memcpy() which would create out of bounds accesses, this was flagged by KASAN. Replace this with strlcpy() to make sure we are bound the source buffer size and we also always NUL-terminate strings.

2016-11-30net: phy: broadcom: Add support code for reading PHY countersFlorian Fainelli
Broadcom PHYs expose a number of PHY error counters: receive errors, false carrier sense, SerDes BER count, local and remote receive errors. Add support code to allow retrieving these error counters. Since the Broadcom PHY library code is used by several drivers, make it possible for them to specify the storage for the software copy of the statistics.

2016-11-24net: phy: broadcom: Allow enabling or disabling of EEEFlorian Fainelli
In preparation for adding support for Wirespeed/downshift, we need to change bcm_phy_eee_enable() to allow enabling or disabling EEE, so make the function take an extra enable/disable boolean parameter and rename it to illustrate it sets EEE, not necessarily just enables it.

2015-10-18net: phy: bcm-phy-lib: Fix module license issueArun Parameswaran
The 'bcm-phy-lib.c', added as a part of the commit "net: phy: Add Broadcom phy library for common interfaces" was missing the module license. This was causing an issue when the library is built as a module; "module license 'unspecified' taints kernel". This patch fixes the issue by adding the module license, author and description to the bcm-phy-lib.c file.
