2016-12-04ARM: dts: dra7xx: sync DT with latest LinuxLokesh Vutla
Sync all dra7xx based dts files with latest Linux Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2016-11-13ARM: dts: dra7xx: Update spi-max-frequency for qspi slave nodeVignesh R
Update the spi-max-frequency property of m25p80 flash slave to match that of TI QSPI controller node, so that QSPI operations happen at maximum supported frequency of 76.8MHz. Signed-off-by: Vignesh R <vigneshr@ti.com> Reviewed-by: Jagan Teki <jteki@openedev.com>
2016-08-12ARM: dts: dra7xx-evm: add evm_3v3_sd regulatorVignesh R
Add a node for evm_3v3_sd using onboard PCF GPIO expander which feeds on to mmc vdd. Update mapping for vmmc-supply and vmmc_aux-supply. evm_3v3_sd supplies to SD card vdd, and ldo1 to sdcard i/o lines. Signed-off-by: Vignesh R <vigneshr@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2016-08-08ARM: dts: dra7xx: Add u-boot specific property for PCF8575 nodesVignesh R
PCF8575 does not have any registers hence, offset field needs to be ignored for i2c read/write. Therefore populate u-boot,i2c-offset-len with 0 in PCF8575 DT nodes. Signed-off-by: Vignesh R <vigneshr@ti.com> Reviewed-by: Mugunthan V N <mugunthanvnm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2016-07-29ARM: dts: dra7xx: Update spi-max-frequency for QSPIVignesh R
According to AM572x DM SPRS953A, QSPI max bus speed is 76.8MHz. Therefore update the spi-max-frequency value of QSPI node for DRA74 and DRA72 evm. This increase flash read speed by ~2MB/s.

2016-07-09ARM: dts: dra7x: Support QSPI MODE-0 operation at 64MHzVignesh R
According to Data Manual(SPRS915P) of AM57x, TI QSPI controller on DRA74(rev 1.1+)/DRA72 EVM can support up to 64MHz in MODE-0, whereas MODE-3 is limited to 48MHz. Hence, switch to MODE-0 for better throughput.

2016-04-18ARM: dts: dra7xx: am57xx: fix cd-gpios definition as per hardware design and ↵Mugunthan V N
dt binding docs As per mmc device tree binding documentation card detect gpio has to be active low signal. When a hardware is designed with active high card detect, gpio polarity has to be changed with cd-inverted dt property. In DRA72x and AM57xx EVMs the card detect gpio is designed as active low gpio. So correcting the dt card detect gpio definition. Also adding card-detect gpio for DRA74x EVM. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
