ilsel_enable_fixed – Enable an ILSEL set at a fixed interrupt level Synopsis int ilsel_enable_fixed(ilsel_source_t set, unsigned int level); Arguments set ILSEL source (see ilsel_source_t enum in include/asm-sh/ilsel.h). level Interrupt level (1 – 15) Description Enables a given ILSEL source at a fixed interrupt level. Necessary both for level reservation as well as for aliased sources…
ilsel_enable – Enable an ILSEL set. Synopsis int ilsel_enable(ilsel_source_t set); Arguments set ILSEL source (see ilsel_source_t enum in include/asm-sh/ilsel.h). Description Enables a given non-aliased ILSEL source (<= ILSEL_KEY) at the highest available interrupt level. Callers should take care to order callsites noting descending interrupt levels. Aliasing FPGA and external board IRQs need to use ilsel_enable_fixed….

ilookup5 – search for an inode in the inode cache Synopsis struct inode *ilookup5(struct super_block *sb, unsigned long hashval, int (*test)(struct inode *, void *), void *data); Arguments sb super block of file system to search hashval hash value (usually inode number) to search for test callback used for comparisons between inodes data opaque data…
ilookup – search for an inode in the inode cache Synopsis struct inode *ilookup(struct super_block *sb, unsigned long ino); Arguments sb super block of file system to search ino inode number to search for Description Search for the inode ino in the inode cache, and if the inode is in the cache, the inode is…
iio_validate_scan_mask_onehot – Validates that exactly one channel is selected Synopsis bool iio_validate_scan_mask_onehot(struct iio_dev * indio_dev, const unsigned long * mask); Arguments indio_dev the iio device mask scan mask to be checked Description Return true if exactly one bit is set in the scan mask, false otherwise. It can be used for devices where only one channel can be active…
