* ARM: OMAP2+: Fix device node reference countsGuenter Roeck2017-03-041-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit 0549bde0fcb1 ("of: fix of_node leak caused in of_find_node_opts_by_path"), the following error may be reported when running omap images. OF: ERROR: Bad of_node_put() on /ocp@68000000 CPU: 0 PID: 0 Comm: swapper Not tainted 4.10.0-rc7-next-20170210 #1 Hardware name: Generic OMAP3-GP (Flattened Device Tree) [<c0310604>] (unwind_backtrace) from [<c030bbf4>] (show_stack+0x10/0x14) [<c030bbf4>] (show_stack) from [<c05add8c>] (dump_stack+0x98/0xac) [<c05add8c>] (dump_stack) from [<c05af1b0>] (kobject_release+0x48/0x7c) [<c05af1b0>] (kobject_release) from [<c0ad1aa4>] (of_find_node_by_name+0x74/0x94) [<c0ad1aa4>] (of_find_node_by_name) from [<c1215bd4>] (omap3xxx_hwmod_is_hs_ip_block_usable+0x24/0x2c) [<c1215bd4>] (omap3xxx_hwmod_is_hs_ip_block_usable) from [<c1215d5c>] (omap3xxx_hwmod_init+0x180/0x274) [<c1215d5c>] (omap3xxx_hwmod_init) from [<c120faa8>] (omap3_init_early+0xa0/0x11c) [<c120faa8>] (omap3_init_early) from [<c120fb2c>] (omap3430_init_early+0x8/0x30) [<c120fb2c>] (omap3430_init_early) from [<c1204710>] (setup_arch+0xc04/0xc34) [<c1204710>] (setup_arch) from [<c1200948>] (start_kernel+0x68/0x38c) [<c1200948>] (start_kernel) from [<8020807c>] (0x8020807c) of_find_node_by_name() drops the reference to the passed device node. The commit referenced above exposes this problem. To fix the problem, use of_get_child_by_name() instead of of_find_node_by_name(); of_get_child_by_name() does not drop the reference count of passed device nodes. While semantically different, we only look for immediate children of the passed device node, so of_get_child_by_name() is a more appropriate function to use anyway. Release the reference to the device node obtained with of_get_child_by_name() after it is no longer needed to avoid another device node leak. While at it, clean up the code and change the return type of omap3xxx_hwmod_is_hs_ip_block_usable() to bool to match its use and the return type of of_device_is_available().

The board however has no EEPROM to store the ethernet MAC address, which is programmed by the boot loader. To allow Linux to use the same MAC address as the boot loader (or for that matter any fixed MAC address), we need a node in the device tree for the ethernet controller that the boot loader can update at runtime with a local-mac-address property. Add it, along with an alias for the ethernet controller to let the boot loader locate it easily.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pinmuxing for DRA7x/AM57x family of processors need to be done in IO isolation as part of initial bootloader executed from SRAM. This is done as part of iodelay configuration sequence and is required due to the limitations introduced by erratum ID: i869[1] (IO Glitches can occur when changing IO settings) and elaborated in the Technical Reference Manual[2] 18.4.6.1.7 Isolation Requirements. Only peripheral that is permitted for dynamic pin mux configuration is MMC and DCAN. MMC is permitted to change to accommodate the requirements for varied speeds (which require IO-delay support in kernel as well). DCAN is a result of i893[1] (DCAN initialization sequence). DCAN pinmux is retained in this patch. MMC pinmux is missing from the dra7-evm.dts file and the board is relying on configuration done by bootloader. A subsequent patch will add MMC pinmux configuration. A side-effect of this patch is that NAND support is removed. NAND pins clash with VOUT3 on DRA7-EVM. U-Boot selects VOUT3 over NAND as per TI EVM application needs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On chiliSOM TPS65217 nWAKEUP pin is connected to AM335x internal RTC EXT_WAKEUP input. In RTC-only state TPS65217 is notifying about power on events (such as power buton presses) by setting nWAKEUP output low. After that it waits 5s for proper device boot. Currently it doesn't happen, as the processor doesn't listen for such events. Consequently TPS65217 changes state from SLEEP (RTC-only state) to OFF. Enable EXT_WAKEUP input of AM335x's RTC, so the processor can properly detect power on events and recover immediately from RTC-only states, without powering off RTC and losing time.

It turns out that smartreflex is still using platform data and produces the following errors during probe: smartreflex smartreflex.0: invalid resource smartreflex smartreflex.0: omap_sr_probe: ioremap fail smartreflex: probe of smartreflex.0 failed with error -22 smartreflex smartreflex.1: invalid resource smartreflex smartreflex.1: omap_sr_probe: ioremap fail smartreflex: probe of smartreflex.1 failed with error -22 Let's fix the regression by adding back the smartreflex hwmod data. The long term is to update the smartreflex driver to use device tree based probing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | What happens is that a write to /dev/sg is given a request with non-zero ->iovec_count combined with zero ->dxfer_len. Or with ->dxferp pointing to an array full of empty iovecs. Having write permission to /dev/sg shouldn't be equivalent to the ability to trigger BUG_ON() while holding spinlocks...

Use WARN_ON() combined with returning an error. Found by Dmitry Vyukov and syzkaller. [ Changed to "WARN_ON_ONCE()". Al has a patch that should fix the root cause, but a BUG_ON() is not acceptable in any case, and a WARN_ON() might still be a cause of excessive log spamming. NOTE! If this warning ever triggers, we may end up leaking resources, since this doesn't bother to try to clean the command up. So this WARN_ON_ONCE() triggering does imply real problems. But BUG_ON() is much worse. People really need to stop using BUG_ON() for "this shouldn't ever happen". It makes pretty much any bug worse. - Linus ] Signed-off-by: Johannes Thumshirn <jthumshirn@suse.de> Reported-by: Dmitry Vyukov <dvyukov@google.com> Cc: James Bottomley <jejb@linux.vnet.ibm.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
