    layerscape: add ls2088ardb device support
    
    The QorIQ LS2088A processor is built on the Layerscape
    architecture combining eight ARM A72 processor cores
    with advanced, high-performance datapath acceleration
    and network, peripheral interfaces required for
    networking, telecom, wireless infrastructure, aerospace
    applications and general-purpose embedded applications.
    
    Features summary:
    - Eight 64-bit ARM v8 Cortex-A72 CPUs
    - Two 64-bit DDR4 SDRAM memory controller with ECC
    - One 32-bit DDR3 SDRAM memory controller with ECC
    - Data path acceleration architecture 2.0 (DPAA2)
    - Ethernet interfaces
    - IFC, 4 PCIe, 2 SATA, 2 USB, 1 SDXC, 2 DUARTs etc

+Subject: [PATCH] mtd: extend physmap_of to let the device tree specify the
+ parition probe
+
+This is to support custom partitioning schemes for embedded PPC. To use
+define your own mtd_part_parser and then add something like:
+	linux,part-probe = "my_probe", "cmdlinepart";
+        To the board's dts file.
+
+If linux,part-probe is not specified then this behaves the same as before.

+Subject: [PATCH 234/238] fsl-ifc: fix compilation error when COMPAT not
+ enabled
+
+When CONFIG_COMPAT is not enabled for cases when 64K pages
+are enabled, there are a series of include dependencies that
+result in some definitions in sched.h that get missed (e.g.
+ TASK_NORMAL).  Explictly include sched.h to resolve this.
+(This seems to be what other drivers do as well)

+Subject: [PATCH 233/238] i2c: pca954x: Add option to skip disabling PCA954x
+ Mux device
+
+On some Layerscape boards like LS2085ARDB/LS2080ARDB,
+input pull-up resistors on PCA954x Mux device are
+missing on board. So, if mux are disabled after powered-on,
+input lines will float leading to incorrect functionality.
+
+Hence, PCA954x Mux device should never be turned-off after
+power-on.
+
+Add option to skip disabling PCA954x Mux device
+if device tree contians "i2c-mux-never-disable" property
+for pca954x device node.

+Subject: [PATCH 237/238] pcie/ls208x: use unified compatible
+ "fsl,ls2080a-pcie" for ls208x
+
+To avoid unnecessary reduplication, let's use unified compatible
+"fsl,ls2080a-pcie" for ls2080a, ls2085a, ls2088a.
+
+This patch fixes issue of pcie not working on ls2088a.
