2020-06-28Merge tag 'omap-for-v5.8/dt-missed-signed' of ↵Arnd Bergmann
git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/omap-fixes Missed sdhci patch for am3 and am4 I forgot to send a pull request earlier for converting am3 and am4 to use sdhci-omap driver instead of the old omap_hsmmc driver. There was a display subsystem related suspend and resume regression found recently and looks like I forgot to send a pull request for this patch while debugging the regression. This patch has been tested without the display subsystem, and has been in Linux next for several weeks now, so would be good to have merged for v5.8. * tag 'omap-for-v5.8/dt-missed-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: Move am33xx and am43xx mmc nodes to sdhci-omap driver Link: https://lore.kernel.org/r/pull-1591637467-607254@atomide.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2020-05-08ARM: dts: am437x: fix networking on boards with ksz9031 phyGrygorii Strashko
Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY") the networking is broken on boards: am437x-gp-evm am437x-sk-evm am437x-idk-evm All above boards have phy-mode = "rgmii" and this is worked before, because KSZ9031 PHY started with default RGMII internal delays configuration (TX off, RX on 1.2 ns) and MAC provided TX delay. After above commit, the KSZ9031 PHY starts handling phy mode properly and disables RX delay, as result networking is become broken. Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous behavior.

Add pinctrl data for ddr_vtt_toggle pin so that it is configured for proper state during DeepSleep0. The pin should enter DS0 off mode and hold the line low so VTT regulator is kept off while suspended. It is also important for the PULLUP to be set on this pin so that on removal of isolation, the VTT line is pulled high as a requirement for bringing the DDR3 out of self-refresh. This toggling is dependent on the IO isolation controlled by the wkup_m3. Without placing the IOs into isolation the DS0 states set for the pin will not be latched into effect during suspend.

2018-07-02ARM: dts: Improve omap l4per idling with wlcore edge sensitive interruptTony Lindgren
The wl1835mod.pdf data sheet says this pretty clearly for WL_IRQ line: "WLAN SDIO out-of-band interrupt line. Set to rising edge (active high) by default." And it seems this interrupt can be optionally configured to use falling edge too since commit bd763482c82e ("wl18xx: wlan_irq: support platform dependent interrupt types"). On omap4, if the wlcore interrupt is configured as level instead of edge, L4PER will stop doing hardware based idling after ifconfig wlan0 down is done and the WL_EN line is pulled down. The symptoms show up with L4PER status registers no longer showing the IDLEST bits as 2 but as 0 for all the active GPIO banks and for L4PER_CLKCTRL. Also the l4per_pwrdm RET count stops increasing in the /sys/kernel/debug/pm_debug/count. While there is also probably a GPIO related issue that needs to be still fixed, this change gets us to the point where we can have L4PER idling. I'm guessing wlcore was at some point configured to use level interrupts because of edge handling issues in gpio-omap. However, with the recent fixes to gpio-omap the edge interrupts seem to be working just fine. Let's change it for all omap boards with wlcore interrupt set as level.

2017-08-14ARM: dts: am437xx: Enable NAND dma prefetch by defaultFranklin S Cooper Jr
Currently the default method of prefetch polled shows the highest possible read and write speed when minimal non NAND background activity is being done. But it is also very CPU intensive to reach these high speeds (CPU load of 99% via mtd performance tests). While DMA prefetch only uses 50% of the CPU to achieve around 23% less in top read and write performance. However, as the non NAND CPU load increases the read and write performance takes a large hit when using polled prefetch. Therefore, prefetch dma mode ends up outperforming prefetch polled in general "system level" test. So switch to using dma prefetch by default since it is likely what most users would prefer.

2015-07-21ARM: dts: am437x: add aliases for all UART instancesSekhar Nori
Add serialN aliases for all 6 UART instances on the AM437x SoC so each board's .dts file does not have to define its own aliases. Remove the alias added for am437x-gp-evm.dts now that we have the aliases defined in am4372.dtsi file. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2015-07-14ARM: dts: am437x-gp-evm: Enable analog audio via simple-cardPeter Ujfalusi
The board uses McASP1 <-> tlv320aic3106 for analog audio and has Headphone out and Line in connectors. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2015-07-14ARM: dts: am437x-gp-evm: McASP1 node for audio supportPeter Ujfalusi
Add node for McASP1 along with the needed pinctrl entries. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2015-07-14ARM: dts: am437x-gp-evm: Add node for tlv320aic3106 audio codecPeter Ujfalusi
Analog audio is using this codec on the board. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2015-07-14ARM: dts: am437x-gp-evm: Rename fixed regulator vmmcsd_fixed to evm_v3_3dPeter Ujfalusi
The same regulator is used by other chips on the board. The power path is: VBAT -> TPS63031 - Enable signal is V1_8D regulator -> V3_3D. V3_3D is used by SD slot and tlv320aic3106 codec as well. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
