From d034f53cc6c5c09a4e10cb9716986f3844c58514 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 17 Dec 2014 14:40:42 +0100 Subject: ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds As of commit 9a1091ef0017c40a ("irqchip: gic: Support hierarchy irq domain."), armadillo-legacy hangs during boot with: sh-tmu.0: ch0: used for clock events sh-tmu.0: ch0: used for periodic clock events sh-tmu.0: ch0: failed to request irq 230 sh-tmu.0: ch1: used as clock source sh-cmt-48.1: ch0: failed to request irq 90 sh-cmt-48.1: ch0: registration failed earlytimer: unable to probe sh-cmt-48 early. Calibrating delay loop... This happens because the IRQ numbers of the GIC are now virtual, and no longer match the hardcoded hardware IRQ numbers in the platform board code. To fix this, instantiate the GIC from platform board code when compiling a legacy kernel, like is done on sh73a0 for kzm9g-legacy.

They were a little unhappy before that change, but after that change they're REALLY unhappy. It turns out that the above fix happens to fix a corruption when reading card information during probe time. Without the fix we didn't detect that high speed SD cards could actually support high speed. With the fix we suddenly detect that they're high speed and we try to use them at 50MHz. That doesn't work so well on EVB with the default drive strength (maybe because there are two physical SD card slots hooked up to the same pin?). Fix the problem by bumping up the drive strength of the sdmmc lines.

Instead the CPU falls back to using an emulation for the 32KHz clock which is SYSCLK1/610. SYSCLK1 is usually 20MHz on boards so far (which gives an emulated frequency of 32.786KHz), but can also be 19.2 or 27MHz which result in much larger drift. Since this is used to drive the master counter at 32.768KHz * 375 / 2 = 6.144MHz, the emulated speed for 20MHz is of by 570ppm, or about 43 seconds per day, and more than the 500ppm NTP is able to tolerate. Checking the CTRL_CORE_BOOTSTRAP register can determine if the CPU is using the real 32.768KHz crystal or the emulated SYSCLK1/610, and by known that the real counter frequency can be determined and used. The real speed is then SYSCLK1 / 610 * 375 / 2 or SYSCLK1 * 75 / 244.

Instead of modelling it as a regulator, the correct approach is to use the 'reset_gpios' property of the "usb-nop-xceiv" node. GPIO1_7 is the reset GPIO for the USB2517 USB hub. As we currently don't have dt bindings to describe a HUB reset, let's keep using the regulator approach. Rename the regulator to 'reg_hub_reset' to better describe its function and bind it with the USB host1 port instead. USB host support has been introduced by commit 9bf206a9d13be3 ("ARM: dts: imx51-babbage: Add USB Host1 support"), which landed in 3.16 and it seems that USB has only been functional due to previous bootloader initialization. With this patch applied we can get USB host to work without relying on the bootloader.

This collides with a lot of assumptions. It only works when using the internal card-detect mechanism and breaks horribly when using either the normal card-detect via the slot-gpio function or via any other pin. Also there is of course no link between the mmc and jtag on the software-side, so the jtag clocks may very well be disabled when the card is ejected and the soc switches back to the jtag pinmux. Leaving the switching function enabled did result in mmc timeouts and rcu stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases, as we expect the devicetree to explicitly select either mmc or jtag pinmuxes anyway.
