d3aa8de6 - staging: axis-fifo: add unspecified HAS_IOMEM dependency

Wed, 11 Dec 2019 19:27:41 +0000

staging: axis-fifo: add unspecified HAS_IOMEM dependencyCurrently CONFIG_XIL_AXIS_FIFO=y implicitly depends onCONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we getthe following build error:ld: drivers/staging/axis-fifo/axis-fifo.o: in function `axis_fifo_probe':drivers/staging/axis-fifo/axis-fifo.c:809: undefined reference to `devm_ioremap_resource'Fix the build error by adding the unspecified dependency.Reported-by: Brendan Higgins Signed-off-by: Brendan Higgins Link: https://lore.kernel.org/r/20191211192742.95699-7-brendanhiggins@google.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/staging/axis-fifo/Kconfig

031ba1fd - staging: remove redundant 'default n' from Kconfig

Fri, 12 Apr 2019 10:13:02 +0000

staging: remove redundant 'default n' from Kconfig'default n' is the default value for any bool or tristate Kconfigsetting so there is no need to write it explicitly.Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOOis not set' for visible symbols") the Kconfig behavior is the sameregardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/staging/axis-fifo/Kconfig

827ad2c7 - staging: axis-fifo: Add elaborate description in Kconfig

99b75a4e - staging: add missing SPDX lines to Kconfig files

Tue, 02 Apr 2019 10:31:48 +0000

staging: add missing SPDX lines to Kconfig filesThere are a few remaining drivers/staging/*/Kconfig files that do nothave SPDX identifiers in them. Add the correct GPL-2.0 identifier tothem to make scanning tools happy.Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/staging/axis-fifo/Kconfig

1beea620 - staging: axis-fifo: add CONFIG_OF dependency

Mon, 04 Mar 2019 19:43:00 +0000

staging: axis-fifo: add CONFIG_OF dependencyWhen building without CONFIG_OF, the compiler loses track of the flowcontrol in axis_fifo_probe(), and thinks that many variables are usedwithout an initialization even though we actually leave the functionbefore the first use:drivers/staging/axis-fifo/axis-fifo.c: In function 'axis_fifo_probe':drivers/staging/axis-fifo/axis-fifo.c:900:5: error: 'rxd_tdata_width' may be used uninitialized in this function [-Werror=maybe-uninitialized] if (rxd_tdata_width != 32) { ^drivers/staging/axis-fifo/axis-fifo.c:907:5: error: 'txd_tdata_width' may be used uninitialized in this function [-Werror=maybe-uninitialized] if (txd_tdata_width != 32) { ^drivers/staging/axis-fifo/axis-fifo.c:914:5: error: 'has_tdest' may be used uninitialized in this function [-Werror=maybe-uninitialized] if (has_tdest) { ^drivers/staging/axis-fifo/axis-fifo.c:919:5: error: 'has_tid' may be used uninitialized in this function [-Werror=maybe-uninitialized]When CONFIG_OF is set, this does not happen, and since the driver cannotwork without it, just add that option as a Kconfig dependency.Signed-off-by: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/staging/axis-fifo/Kconfig

4a965c5f - staging: add driver for Xilinx AXI-Stream FIFO v4.1 IP core

Mon, 23 Jul 2018 01:27:37 +0000

staging: add driver for Xilinx AXI-Stream FIFO v4.1 IP coreThis IP core has read and write AXI-Stream FIFOs, the contents of which canbe accessed from the AXI4 memory-mapped interface. This is useful fortransferring data from a processor into the FPGA fabric. The driver createsa character device that can be read/written to with standardopen/read/write/close.See Xilinx PG080 document for IP details.https://www.xilinx.com/support/documentation/ip_documentation/axi_fifo_mm_s/v4_1/pg080-axi-fifo-mm-s.pdfThe driver currently supports only store-forward mode with a 32-bitAXI4 Lite interface. DOES NOT support: - cut-through mode - AXI4 (non-lite)Signed-off-by: Jacob Feder Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/staging/axis-fifo/Kconfig
