  • 9ab921201   cpm_uart: fix non-console port startup bug ... Browse Code »

    After UART interrupt handler is installed and rx is enabled, if an rx
    interrupt comes before hardware init, rx->cur will be updated. Then the
    hardware init will reset BD and make rx->cur out of sync, move the hardware
    init code before request_irq.

    …/git/tip/linux-2.6-tip

    This merges branches irq/genirq, irq/sparseirq-v4, timers/hpet-percpu
    and x86/uv.

    The sparseirq branch is just preliminary groundwork: no sparse IRQs are
    actually implemented by this tree anymore - just the new APIs are added
    while keeping the old way intact as well (the new APIs map 1:1 to
    irq_desc[]). The 'real' sparse IRQ support will then be a relatively
    small patch ontop of this - with a v2.6.29 merge target.

  • 80776554b   cpm_uart: Add generic clock API support to set baudrates ... Browse Code »

    This patch introduces baudrate setting support via the generic clock API.
    When present the optional device tree clock property is used instead of
    fsl-cpm-brg. Platforms can then define complex clock schemes, to output
    the serial clock on an external pin for instance.

    This patch replaces the get_mctrl/set_mctrl stubs with modem control line
    read/write access through the GPIO lib.

    Available modem control lines are described in the device tree using GPIO
    bindings. The driver expect a GPIO pin for each of the CTS, RTS, DCD, DSR,
    DTR and RI signals. Unused control lines can be left out.

  • d464df266   [POWERPC] cpm_uart: Allocate DPRAM memory for SMC ports on CPM2-based platforms. ... Browse Code »

    This patch allocates parameter RAM for SMC serial ports without relying on
    previous initialisation by a boot loader or a wrapper layer.

    SMC parameter RAM on CPM2-based platforms can be allocated anywhere in the
    general-purpose areas of the dual-port RAM. The current code relies on the
    boot loader to allocate a section of general-purpose CPM RAM and gets the
    section address from the device tree.

    This patch modifies the device tree address usage to reference the SMC
    parameter RAM base pointer instead of a pre-allocated RAM section and
    allocates memory from the CPM dual-port RAM when initialising the SMC port.
    CPM1-based platforms are not affected.

  • 15f8c604a   [POWERPC] cpm: Describe multi-user ram in its own device node. ... Browse Code »

    The way the current CPM binding describes available multi-user (a.k.a.
    dual-ported) RAM doesn't work well when there are multiple free regions,
    and it doesn't work at all if the region doesn't begin at the start of
    the muram area (as the hardware needs to be programmed with offsets into
    this area). The latter situation can happen with SMC UARTs on CPM2, as its
    parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't
    support moving it.

    It is now described with a muram node, similar to QE. The current CPM
    binding is sufficiently recent (i.e. never appeared in an official release)
    that compatibility with existing device trees is not an issue.

    The code supporting the new binding is shared between cpm1 and cpm2, rather
    than remain separated. QE should be able to use this code as well, once
    minor fixes are made to its device trees.

    in cpm_uart_cpm1.h, DPRAM_BASE is assigned an address derived from cpmp.
    On ARC=ppc, this is a physical address with 1:1 DMA mapping which can't

    returned by cpm_dpram_addr. This patch changes the assignment to use
    cpm_dpram_addr as well, like in cpm_uart_cpm2.h.

  • 4c35630cc   [POWERPC] Change rheap functions to use ulongs instead of pointers ... Browse Code »

    The rheap allocation functions return a pointer, but the actual value is based
    on how the heap was initialized, and so it can be anything, e.g. an offset
    into a buffer. A ulong is a better representation of the value returned by
    the allocation functions.

    This patch changes all of the relevant rheap functions to use a unsigned long
    integers instead of a pointer. In case of an error, the value returned is
    a negative error code that has been cast to an unsigned long. The caller can
    use the IS_ERR_VALUE() macro to check for this.

    All code which calls the rheap functions is updated accordingly. Macros
    IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE().

    Also added error checking to rh_attach_region().

    Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the
    current kernel. Current patch fixes it, as well as other inconsistencies
    expressed, that do not permit targets from working properly:

    - Updated dts with a chosen node with interrupt controller,
    - fixed messed device IDs among CPM2 SoC devices,
    - corrected odd header name and fixed type in defines,
    - Added 82xx subdir to the powerpc/platforms Makefile, missed during
    initial commit,
    - new solely-powerpc header file for 8260 family (was using one from
    arch/ppc, this one cleaned up from the extra stuff), in fact for now
    a placeholder to get the board-specific includes for stuff not yet
    capable to live with devicetree peeks only
    - Fixed couple of misprints in reference mpc8272 dts.
