* board: ks2: Enable ECC using detected DDR sizeLokesh Vutla2016-10-01-0/+3
| | | | | | | | | EEC is being enabled based on the ddr size populated by SPD data. But not all keystone platforms have SPD data to detect ddr3 size. So, enable ECC using the detected DDR size. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>

* disk: part: implement generic function part_get_info_by_name()Petr Kulhavy2016-10-01-33/+53
| | | | | | | | | | | | | | | | | So far partition search by name has been supported only on the EFI partition table. This patch extends the search to all partition tables. Rename part_get_info_efi_by_name() to part_get_info_by_name(), move it from part_efi.c into part.c and make it a generic function which traverses all part drivers and searches all partitions (in the order given by the linked list). For this a new variable struct part_driver.max_entries is added, which limits the number of partitions searched. For EFI this was GPT_ENTRY_NUMBERS. Similarly the limit is defined for DOS, ISO, MAC and AMIGA partition tables.

In practice, various code is missing, and various configuration options are not enabled, which causes U-Boot to hang when attempting to initialize this USB port. This patch enables ULPI PHY support on Ventana, and adds the required pinmux setup for the port to operate. Note that Ventana is so similar to Seaboard that this change is made in the Seaboard board file, which is shared with Ventana. Seaboard also has the ULPI USB port wired up in hardware, although to an internal port that often doesn't have anything attached to it. However, the DT nodes for the USB controller and PHY had different status property values, so the port was not initialized by U-Boot. Fix this inconsistency, and enable the ULPI port, just like in the Linux kernel DT. This likewise requires enabling ULPI support in the Seaboard defconfig.

This patch fixes that. For example, this avoids the following message while booting on Ventana, which is caused by the fact that the USB0 controller had no alias, and defaulted to wanting a sequence number of 0, which was later explicitly requested by the alias for USB controller 2. USB2: Device 'usb@c5008000': seq 0 is in use by 'usb@c5000000' This didn't affect USB operation in any way though. Related, there's no need for the USB controller aliases to have an order that's different from the HW order, so re-order any aliases to match the HW ordering. This has the benefit that since USB controller 0 is the only one that supports device-mode in HW, and U-Boot only supports enabling device move on controller 0, there's now good synergy in the ordering! For Tegra20, that's not relevant at present since USB device mode doesn't work correctly on that SoC, but it will save some head-scratching later. This patch doesn't fix the colibri_t20 board, even though it has the same issue, since Marcel already sent a patch for that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB ULPI PHY reset signals are typically active low. Consequently, they should be marked as GPIO_ACTIVE_LOW in device tree, and indeed they are in the Linux kernel DTs, and in DT properties that U-Boot doesn't yet use. However, in DT properties that U-Boot does use, the value has been set to 0 (== GPIO_ACTIVE_HIGH) to work around a bug in U-Boot. This change fixes the DT to correctly represent the HW, and fixes the Tegra USB driver to cope with the fact that dm_gpio_set_value() internally handles any inversions implied by the DT value GPIO_ACTIVE_LOW.

This change is a rather horrible hack, as explained in the comment added to the clock driver. I've tried fixing this correctly for all clocks as described in that comment, but there's too much fallout elsewhere. I believe the clock driver has a number of bugs which all cancel each-other out, and unravelling that chain is too complex at present. This change is the smallest change that fixes clock_get_periph_rate() for UART clocks while guaranteeing no change in behaviour for any other clock, which avoids other regressions.

| * | clock: implement a driver for the Tegra CARStephen Warren2016-09-27-0/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a clock uclass driver for the Tegra CAR. This allows clients to use standard clock APIs on Tegra. This device is intended to be instantiated by the core Tegra CAR driver, rather than being instantiated directly from DT. The implementation uses the existing custom Tegra- specific clock APIs to avoid coupling the series with significant refactoring of the existing Tegra clock/clock code. The driver currently only supports peripheral clocks, and avoids support for other clocks such as PLLs and external clocks. This should be sufficient to convert over all Tegra peripheral drivers, and avoids a complex implementation which calls different Tegra-specific clock APIs based on the type of clock being manipulated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tegra CAR (Clock And Reset) module provides control of most clocks and reset signals within the Tegra SoC. This change implements a driver for this module. However, since the module implements multiple kinds of services (clocks, resets, perhaps more), all this driver does is bind various sub-devices, which in turn provide the real services. This driver is essentially an "MFD" (Multi-Function Device) in Linux kernel speak. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

That driver will call into Tegra's existing clock code to simplify the transition; this avoids tieing the clock uclass patches into significant refactoring of the existing custom clock API implementation. Some of the Tegra clock APIs that manipulate peripheral clocks require both the peripheral clock ID and parent clock ID to be passed in together. However, the clock uclass API does not require any such "parent" parameter, so the clock driver must determine this information itself. This patch implements new Tegra- specific clock API clock_get_periph_parent() for this purpose. The new API is implemented in the core Tegra clock code rather than SoC- specific clock code. The implementation uses various SoC-/clock-specific data. That data is only available in SoC-specific clock code. Consequently, two new internal APIs are added that enable the core clock code to retrieve this information from the SoC-specific clock code. Due to the structure of the Tegra clock code, this leads to some unfortunate code duplication. However, this situation predates this patch. Ideally, future work will de-duplicate the Tegra clock code, and migrate it into drivers/clk/tegra. However, such refactoring is kept separate from this series.

Aspect 1 is reasonable, but aspect 2 is a system-level decision, not something that an individual peripheral driver should in general know about or influence. Such system-level knowledge ties the driver to a specific SoC implementation, even when they use generic APIs for clock manipulation, since they must have SoC-specific knowledge such as parent clock IDs. Limited exceptions exist, such as where peripheral HW is expected to dynamically switch between clock sources at run-time, such as CPU clock scaling or display clock conflict management in a multi-head scenario. This patch enhances the Tegra core code to perform system-level clock tree setup, in a similar fashion to the Linux kernel Tegra clock driver. This will allow future patches to simplify peripheral drivers by removing the clock parent setup logic. This change is required prior to converting peripheral drivers to use the standard clock APIs, since: 1) The clock uclass doesn't currently support a set_parent() operation. Adding one is possible, but not necessary at the moment. 2) The clock APIs retrieve all clock IDs from device tree, and the DT bindings for almost all peripherals only includes information about the relevant peripheral clocks, and not any potential parent clocks.

U-Boot doesn't use DMA so isn't affected. * Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all information required by U-Boot, so U-Boot is not affected. * Conversion of many magic numbers to named defines. * Addition of many nodes not used by U-Boot, including separation of the Tegra LIC (Legacy IRQ controller) and GIC. * Node sort order fixes. Remaining deltas relative to the Linux DT: * U-Boot has enabled PCIe for Tegra210, but the kernel hasn't yet. * The GPIO node compatible value in the kernel explicitly includes Tegra124 values whereas U-Boot does not.

However, I'd rather this change be a no-op, and any DT bug-fixes be separate. * Sync misc changes from the kernel: missing DT content, minor compatible value fixes, typos. Remaining deltas relative to the Linux DT: * U-Boot uses #address-cells/#size-cells of 1 whereas the kernel uses 2. I believe U-Boot's DT parsing currently assumes that these values match the physical address size, so I didn't synchronize this part of the DT. * U-Boot uses the original XUSB PHY DT binding, wherease the kernel DT has moved to a newer version. Thus, XUSB client nodes include properties names phys and phy-names that do not appear in the kernel, and don't include pad definitions in the padctl node.
