* ARM: dts: Improve omap l4per idling with wlcore edge sensitive interruptTony Lindgren2018-07-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
