10 years agoARM: tegra: use a CPU freq that all SKUs can support
Stephen Warren [Thu, 8 May 2014 15:33:45 +0000 (09:33 -0600)]
ARM: tegra: use a CPU freq that all SKUs can support

U-Boot on Tegra30 currently selects a main CPU frequency that cannot be
supported at all on some SKUs, and needs higher VDD_CPU/VDD_CORE values
on some others. This can result in unreliable operation of the main CPUs.

Resolve this by switching to a CPU frequency that can be supported by any
SKU. According to the following link, the maximum supported CPU frequency
of the slowest Tegra30 SKU is 600MHz:

repo http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=summary
branch l4t/l4t-r16-r2
path arch/arm/mach-tegra/tegra3_dvfs.c
table cpu_dvfs_table[]

According to that same table, the minimum VDD_CPU required to operate at
that frequency across all SKUs is 1.007V. Given the adjustment resolution
of the TPS65911 PMIC that's used on all Tegra30-based boards we support,
we'll end up using 1.0125V instead.

At that VDD_CPU, tegra3_get_core_floor_mv() in that same file dictates
that VDD_CORE must be at least 1.2V on all SKUs. According to
tegra_core_speedo_mv() (in tegra3_speedo.c in the same source tree),
that voltage is safe for all SKUs.

An alternative would be to port much of the code from tegra3_dvfs.c and
tegra3_speedo.c in the kernel tree mentioned above. That's more work
than I want to take on right now.

While all the currently supported boards use the same regulator chip for
VDD_CPU, different types of regulators are used for VDD_CORE. Hence, we
add some small conditional code to select how VDD_CORE is programmed. If

the IP core to what U-Boot supports today.

In this variant, at least the following difference are present:
- Some registers are moved about.
- Setup transaction completion is reported in a separate 'epsetupstat'
  register, rather than in 'epstat' (which still exists, perhaps for
  other transaction types).
- USB connection speed is reported in a separate 'hostpc1_devlc'
  register, rather than 'portsc'.
- The registers used by ci_udc.c begin at offset 0x130 from the USB
  register base, rather than offset 0x140. However, this is handled
  by the associated EHCI controller driver, since the register address
  is stored in controller.ctrl->hcor.

Introduce define CONFIG_CI_UDC_HAS_HOSTPC to indicate which variant of
the controller should be supported. The "HAS_HOSTPC" part of this name
mirrors the similar "has_hostpc" field used by the Linux EHCI controller

Ideally, I believe that the PHY initialization code should be part of
ehci_hcd_init() in the relevant EHCI controller driver, or some board-
specific function that ehci_hcd_init() calls.

For MX6, I'm not sure this PHY initialization code is correct even before
this patch, since ehci-mx6's ehci_hcd_init() already configures PORTSC to
a board-specific value, and it seems likely that the code in ci_udc.c is
incorrectly undoing this. Perhaps this is not an issue if the PHY
