* | ARM: tegra: remove stale nvidia, bpmp I2C DT propertyStephen Warren2016-08-25-10/+0
| | | | | | | | | | | | | | | | | | | | The nvidia,bpmp property is left over from an old BPMP I2C binding, and shouldn't be present. Remove it from the SoC DT file, and update the I2C driver not to parse it; the value wasn't used for anything any more anyway.

* net: davinci_emac: Restore the internal MDIO accessors return valueskarl beldan2016-08-22-7/+6
| | | | | | | | | | | | | | | | | The spatch series converting legacy drivers from miiphy_register to mdio_register changed the return convention of the davinci_emac internal MDIO accessors, making the internal code relying on it misbehaving: no mdiodev get registered and U-Boot crashes when using net cmds in the context of the old legacy net API. ATM davinci_emac_initialize and cpu_eth_init don't return a proper value in that case but fixing them would not avoid the crash. This change is just a follow-up to the spatch pass, the MDIO accessors of the mdiodev introduced by the spatch pass retain their proper values.

Commit 3e7d940 ("dm: tpm: Every TPM drivers should depends on DM_TPM") then made DM_I2C a dependency of the driver, effectively forcing users to turn on CONFIG_DM_I2C_COMPAT to get it to work. This patch adds the necessary dm_i2c_write/dm_i2c_read calls to make the driver compatible with DM, but also keeps the legacy calls in ifdefs, so that the driver is now compatible with both DM and non-DM setups.
